-&lt;p&gt;For noen dager siden ble jeg tipset om en ny norsk webtjeneste for
-å holde styr på ens tegneseriesamling.  Har så smått begynt å
-teste den og lagt inn noen hundre oppføringer, og det ser ut til å
-fungere fint.  Utvikleren, Trond Hallstensen, er selv ivrig samler og
-har laget systemet i første omgang for seg selv, men altså gjort det
-mulig også for andre å bidra.  Tjenesten har potensiale til å bli
-en komplett og verdifull tegneserieindeks over norske serier.  Da jeg
-oppdaget tjenesten var det endel mangler som gjorde meg skeptisk til
-å registrere min samling der.  Det var nemlig ingen måte å hente ut
-en maskinlesbar oversikt over det jeg registrerte, slik at mine data
-ville være innelåst i tjenesten.  Siden den gang har Trond lagt til
-en eksportfunksjon til CSV-format, slik at i hvert fall noen av
-feltene i databasen kan hentes ut for mine serier.  Pr. i dag er det
-serie, seriegruppe, år, nr og tittel_på_forside.&lt;/p&gt;
-
-&lt;p&gt;Prinsipielt ønsker jeg å kunne hente ut alle feltene om en
-tegneserie, for å unngå repetisjon av det som skjedde med IMDB og
-CDDB på 90-tallet.  Begge begynte som fellesskapsprosjekter der
-brukerne bidro på like vilkår, og ble lukket inne da
-initiativtageren og innehaveren av maskinen der tjenesten kjørte
-hadde fått nok innhold til at de ikke lenger følte at de trengte å
-behandle brukerne som likemenn.  Trond har skrevet til meg at flere
-felter vil bli lagt inn i eksporten (blant annet strekkode), men
-uttrykt skepsis til å gjøre all informasjonen tilgjengelig (han
-ønsker slik jeg forsto han å kontrollere tjenesten og ikke gjøre
-det mulig å lage konkurrerende tjeneste).  Holdningen gjør meg ennå
-mer skeptisk, men tjenesten fungerer fint, så jeg har bestemt meg for
-å ta den i bruk, men begrense meg til å registrere informasjon som
-er tilgjengelig i eksporten.&lt;/p&gt;
-
-&lt;p&gt;Har ennå ikke begynt masseregistrering, da jeg venter på støtte for
-strekkoder i tjenesten.  Har strekkodeleser, og vil spare litt tid i
-registreringen når jeg går løs på mine esker.  Foreløbig har jeg
-registrert litt tilfeldige serier som ligger rundt om i huset, men for
-å få et komplett arkiv må nok noen tusen tegneserier registreres.&lt;/p&gt;
-
-&lt;p&gt;Løsningen er i følge utvikleren laget med et Oracle-spesifikt
-verktøy for å lage webtjenester, og ikke fri programvare.
-Utvikleren tar imot innspill men det hørtes ikke ut som om utvikling
-av systemet var enkelt å dele mellom flere, slik at det må via
-ham.&lt;/p&gt;
-
-&lt;p&gt;Høres dette interessant ut, besøk
-&lt;a href=&quot;http://www.mineserier.no/&quot;&gt;mineserier.no&lt;/a&gt; og ta en
-titt.&lt;/p&gt;
+&lt;p&gt;Det står dårlig til med toget når en finner på å la det
+&lt;a href=&quot;http://www.aftenposten.no/nyheter/iriks/article3677060.ece&quot;&gt;kappkjøre
+med sykkel&lt;/a&gt;...  Jeg tror det trengs strukturendringer for å få
+fikset på togproblemene i Norge.&lt;/p&gt;
+
+&lt;p&gt;Mon tro hva toglinje mellom Narvik og Tromsø ville hatt slags
+effekt på området der?&lt;/p&gt;

-og
-&lt;a href=&quot;http://blogg.karlsbakk.net/2009/02/28/nsb-ruter-og-flexus/&quot;&gt;flere&lt;/a&gt;
-protesterer på den massive overvåkningen og registrering av
-trafikkmønster i kollektivtrafikken som planlegges i Oslo.  Det er
-bra.  Jeg mister lysten til å bruke kollektivtransport når jeg ser
-hvordan trafikkselskapet holder på.  Jeg forventer og forlanger å
-ikke bli overvåket med mindre jeg mistenkes for å ha gjort noe
-alvorlig galt.  Den massive registreringen av hvor og når
-passasjerene reiser med kollektivtrafikk som planegges av Ruter i Oslo
-er et grotesk overgrep mot alle som bruker buss, trikk T-bane og tog i
-Osloområdet.&lt;/p&gt;
+&lt;p&gt;It is strange to watch how a bug in Debian causing KDM to fail to
+start at boot when an NVidia video card is used is handled.  The
+problem seem to be that the nvidia X.org driver uses a long time to
+initialize, and this duration is longer than kdm is configured to
+wait.&lt;/p&gt;
+
+&lt;p&gt;I came across two bugs related to this issue,
+&lt;a href=&quot;http://bugs.debian.org/583312&quot;&gt;#583312&lt;/a&gt; initially filed
+against initscripts and passed on to nvidia-glx when it became obvious
+that the nvidia drivers were involved, and
+&lt;a href=&quot;http://bugs.debian.org/524751&quot;&gt;#524751&lt;/a&gt; initially filed against
+kdm and passed on to src:nvidia-graphics-drivers for unknown reasons.&lt;/p&gt;
+
+&lt;p&gt;To me, it seem that no-one is interested in actually solving the
+problem nvidia video card owners experience and make sure the Debian
+distribution work out of the box for these users.  The nvidia driver
+maintainers expect kdm to be set up to wait longer, while kdm expect
+the nvidia driver maintainers to fix the driver to start faster, and
+while they wait for each other I guess the users end up switching to a
+distribution that work for them.  I have no idea what the solution is,
+but I am pretty sure that waiting for each other is not it.&lt;/p&gt;
+
+&lt;p&gt;I wonder why we end up handling bugs this way.&lt;/p&gt;

                <description>

-&lt;p&gt;I 2004 fikk jeg med meg en forelesning om 3D-printing under &lt;a
-href=&quot;http://wiki.oreillynet.com/eurofoo/index.cgi&quot;&gt;euro foo camp&lt;/a&gt;
-der jeg lærte mye nytt om 3D-printing.  Fikk se et lite sjakktårn
-skrevet ut i plast, med vindeltrapp på innsiden av tårnet, og en hul
-gummiball som også var skrevet ut (med et lite hull for å få ut
-fyllmassen).  Ble fortalt at det amerikanske kavaleriet skriver ut
-reservedeler i metall i felt, og at det fantes amerikanske husbyggere
-som eksperimenterer med utskrift av hus.  De to siste har jeg ikke
-funnet noen referanser til i ettertid, og har derfor lurt på om det
-stemmer.  Teknologisk skulle det ikke være noe i veien for slike
-løsninger, det er kun et spørmål om pris på skrivehoder og
-skrivere.  I dag ble jeg tipset om en løsning som
-&lt;a href=&quot;http://www.shapeways.com/blog/archives/217-3D-printing-buildings-interview-with-Enrico-Dini-of-D_Shape.html&quot;&gt;kan
-skrive ut hus&lt;/a&gt;, med sand og bindemiddel i 25 DPI oppløsning.  Mon
-tro om det er fremtidens byggemetode.&lt;/p&gt;
-
-&lt;p&gt;Jeg er ikke i tvil om at 3D-utskrift vil føre til endringer i
-hvordan produksjon gjøres, og at tilgjengeligheten på en rekke produkter
-som i dag er vanskelig eller umulig å få tak i vil bedre seg.  Men de
-som tror at 3D-skrivere vil gjøre fabrikkene overflødige, tror jeg har
-forregnet seg.  3D-skrivere er fantastisk bra til å lage spesielle
-dingser på forespørsel, f.eks. etter å ha lastet ned et 3D-design fra
-tjenester som &lt;a href=&quot;http://www.thingiverse.com/&quot;&gt;Thingiverse&lt;/a&gt;.
-De er derimot ikke spesielt bra til å lage mange eksemplarer av samme
-dings.  Lav pris pr. enhet er fabrikkenes fortrinn.  Hvis det skal
-lages tusenvis, eller millioner av en dings, så vil fabrikkene
-sannsynligvis fortsette å slå 3D-skriving ned i støvlene
-økonomisk, selv om en tar hensyn til transport og logistikk.  Hvis
-det derimot skal lages en håndfull, så vil 3D-skriving fremstå som
-et suverent alternativ.  3D-skriving er i så måte løsning for
-&lt;a href=&quot;http://en.wikipedia.org/wiki/The_Long_Tail&quot;&gt;den lange
-halen&lt;/a&gt;, mens fabrikker nok fortsatt vil være løsningen for
-massemarkedet.&lt;/p&gt;
+&lt;p&gt;A few days ago, parallel booting was enabled in Debian/testing.
+The feature seem to hold up pretty well, but three fairly serious
+issues are known and should be solved:
+
+&lt;p&gt;&lt;ul&gt;
+
+&lt;li&gt;The wicd package seen to
+&lt;a href=&quot;http://bugs.debian.org/508289&quot;&gt;break NFS mounting&lt;/a&gt; and
+&lt;a href=&quot;http://bugs.debian.org/581586&quot;&gt;network setup&lt;/a&gt; when
+parallel booting is enabled.  No idea why, but the wicd maintainer
+seem to be on the case.&lt;/li&gt;
+
+&lt;li&gt;The nvidia X driver seem to
+&lt;a href=&quot;http://bugs.debian.org/583312&quot;&gt;have a race condition&lt;/a&gt;
+triggered more easily when parallel booting is in effect.  The
+maintainer is on the case.&lt;/li&gt;
+
+&lt;li&gt;The sysv-rc package fail to properly enable dependency based boot
+sequencing (the shutdown is broken) when old file-rc users
+&lt;a href=&quot;http://bugs.debian.org/575080&quot;&gt;try to switch back&lt;/a&gt; to
+sysv-rc.  One way to solve it would be for file-rc to create
+/etc/init.d/.legacy-bootordering, and another is to try to make
+sysv-rc more robust.  Will investigate some more and probably upload a
+workaround in sysv-rc to help those trying to move from file-rc to
+sysv-rc get a working shutdown.&lt;/li&gt;
+
+&lt;/ul&gt;&lt;/p&gt;
+
+&lt;p&gt;All in all not many surprising issues, and all of them seem
+solvable before Squeeze is released.  In addition to these there are
+some packages with bugs in their dependencies and run level settings,
+which I expect will be fixed in a reasonable time span.&lt;/p&gt;
+
+&lt;p&gt;If you report any problems with dependencies in init.d scripts to
+the BTS, please usertag the report to get it to show up at
+&lt;a href=&quot;http://bugs.debian.org/cgi-bin/pkgreport.cgi?users=initscripts-ng-devel@lists.alioth.debian.org&quot;&gt;the
+list of usertagged bugs related to this&lt;/a&gt;.&lt;/p&gt;
+
+&lt;p&gt;Update: Correct bug number to file-rc issue.&lt;/p&gt;

-
-&lt;li&gt;&lt;a href=&quot;http://www.aftenposten.no/meninger/kronikker/article3066834.ece&quot;&gt;Jeg, et offer&lt;/a&gt;
-&lt;br&gt;Aage Borchgrevink drodler om offerrollens framvekst i den norske
-offentligheten.&lt;/li&gt;
+&lt;p&gt;After a long break from debian-installer development, I finally
+found time today to return to the project.  Having to spend less time
+working dependency based boot in debian, as it is almost complete now,
+definitely helped freeing some time.&lt;/p&gt;

 
 

-&lt;li&gt;&lt;a href=&quot;http://www.nuug.no/pub/video/published/200904-goopen.html&quot;&gt;Opptak fra Go Open 2009 på web&lt;/a&gt;
-&lt;br&gt;Endelig kan jeg få med meg foredragene jeg gikk glipp av.&lt;/li&gt;
+&lt;p&gt;A while back, I ran into a problem while working on Debian Edu.  We
+include some firmware packages on the Debian Edu CDs, those needed to
+get disk and network controllers working.  Without having these
+firmware packages available during installation, it is impossible to
+install Debian Edu on the given machine, and because our target group
+are non-technical people, asking them to provide firmware packages on
+an external medium is a support pain.  Initially, I expected it to be
+enough to include the firmware packages on the CD to get
+debian-installer to find and use them.  This proved to be wrong.
+Next, I hoped it was enough to symlink the relevant firmware packages
+to some useful location on the CD (tried /cdrom/ and
+/cdrom/firmware/).  This also proved to not work, and at this point I
+found time to look at the debian-installer code to figure out what was
+going to work.&lt;/p&gt;

 
 

-&lt;li&gt;&lt;a href=&quot;http://www.robweir.com/blog/2009/05/update-on-odf-spreadsheet.html&quot;&gt;MS Excel 2007 håndterer ODF dårlig&lt;/a&gt;
-&lt;br&gt;Microsoft har lykkes med å implementere ODF slik at de ikke
-samhandler med noen av de andre som håndterer ODF-regneark.&lt;/li&gt;
+&lt;p&gt;The firmware loading code is in the hw-detect package, and a closer
+look revealed that it would only look for firmware packages outside
+the installation media, so the CD was never checked for firmware
+packages.  It would only check USB sticks, floppies and other
+&quot;external&quot; media devices.  Today I changed it to also look in the
+/cdrom/firmware/ directory on the mounted CD or DVD, which should
+solve the problem I ran into with Debian edu.  I also changed it to
+look in /firmware/, to make sure the installer also find firmware
+provided in the initrd when booting the installer via PXE, to allow us
+to provide the same feature in the PXE setup included in Debian
+Edu.&lt;/p&gt;

 
 

-&lt;li&gt;&lt;a href=&quot;http://www.groklaw.net/article.php?story=20090503215045379&quot;&gt;MS
-Word 2007 håndterer ODF dårlig&lt;/a&gt;
-&lt;br&gt;Fotnoter laget i MS Office blir merkelige i OpenOffice.org.&lt;/li&gt;
+&lt;p&gt;To make sure firmware deb packages with a license questions are not
+activated without asking if the license is accepted, I extended
+hw-detect to look for preinst scripts in the firmware packages, and
+run these before activating the firmware during installation.  The
+license question is asked using debconf in the preinst, so this should
+solve the issue for the firmware packages I have looked at so far.&lt;/p&gt;

 
 

-&lt;/ul&gt;
+&lt;p&gt;If you want to discuss the details of these features, please
+contact us on debian-boot@lists.debian.org.&lt;/p&gt;

-&lt;p&gt;Kom over
-&lt;a href=&quot;http://news.cnet.com/8301-13505_3-10216873-16.html&quot;&gt;interessante
-tall&lt;/a&gt; fra IDG om utviklingen av linuxservermarkedet.  Fikk meg til
-å tenke på antall tjenermaskiner ved Universitetet i Oslo der jeg
-jobber til daglig.  En rask opptelling forteller meg at vi har 490
-(61%) fysiske unix-tjener (mest linux men også noen solaris) og 196
-(25%) windowstjenere, samt 112 (14%) virtuelle unix-tjenere.  Med den
-bakgrunnskunnskapen kan jeg godt tro at IDG er inne på noe.&lt;/p&gt;
+&lt;p&gt;For en stund tilbake kjøpte jeg en magnetkortleser for å kunne
+titte på hva som er skrevet inn på magnetstripene til ulike kort.  Har
+ikke hatt tid til å analysere mange kort så langt, men tenkte jeg
+skulle dele innholdet på to kort med mine lesere.&lt;/p&gt;
+
+&lt;p&gt;For noen dager siden tok jeg flyet til Harstad og Hurtigruten til
+Bergen.  Flytoget fra Oslo S til flyplassen ga meg en billett med
+magnetstripe.  Påtrykket finner jeg følgende informasjon:&lt;/p&gt;
+
+&lt;pre&gt;
+Flytoget Airport Express Train
+
+Fra - Til        : Oslo Sentralstasjon
+Kategori         : Voksen
+Pris             : Nok 170,00
+Herav mva. 8,00% : NOK 12,59

+Billetttype      : Enkeltbillett
+
+102-1015-100508-48382-01-08
+&lt;/pre&gt;

-&lt;p&gt;&lt;a href=&quot;http://www.dagensit.no/trender/article1658676.ece&quot;&gt;Dagens
-IT melder&lt;/a&gt; at Intel hevder at det er dyrt å miste en datamaskin,
-når en tar tap av arbeidstid, fortrolige dokumenter,
-personopplysninger og alt annet det innebærer.  Det er ingen tvil om
-at det er en kostbar affære å miste sin datamaskin, og det er årsaken
-til at jeg har kryptert harddisken på både kontormaskinen og min
-bærbare.  Begge inneholder personopplysninger jeg ikke ønsker skal
-komme på avveie, den første informasjon relatert til jobben min ved
-Universitetet i Oslo, og den andre relatert til blant annet
-foreningsarbeide.  Kryptering av diskene gjør at det er lite
-sannsynlig at dophoder som kan finne på å rappe maskinene får noe ut
-av dem.  Maskinene låses automatisk etter noen minutter uten bruk,
-og en reboot vil gjøre at de ber om passord før de vil starte opp.
-Jeg bruker Debian på begge maskinene, og installasjonssystemet der
-gjør det trivielt å sette opp krypterte disker.  Jeg har LVM på toppen
-av krypterte partisjoner, slik at alt av datapartisjoner er kryptert.
-Jeg anbefaler alle å kryptere diskene på sine bærbare.  Kostnaden når
-det er gjort slik jeg gjør det er minimale, og gevinstene er
-betydelige.  En bør dog passe på passordet.  Hvis det går tapt, må
-maskinen reinstalleres og alt er tapt.&lt;/p&gt;
-
-&lt;p&gt;Krypteringen vil ikke stoppe kompetente angripere som f.eks. kjøler
-ned minnebrikkene før maskinen rebootes med programvare for å hente ut
-krypteringsnøklene.  Kostnaden med å forsvare seg mot slike angripere
-er for min del høyere enn gevinsten.  Jeg tror oddsene for at
-f.eks. etteretningsorganisasjoner har glede av å titte på mine
-maskiner er minimale, og ulempene jeg ville oppnå ved å forsøke å
-gjøre det vanskeligere for angripere med kompetanse og ressurser er
-betydelige.&lt;/p&gt;
+&lt;p&gt;Today, the last piece of the puzzle for roaming laptops in Debian
+Edu finally entered the Debian archive.  Today, the new
+&lt;a href=&quot;http://packages.qa.debian.org/libp/libpam-mklocaluser.html&quot;&gt;libpam-mklocaluser&lt;/a&gt;
+package was accepted.  Two days ago, two other pieces was accepted
+into unstable.  The
+&lt;a href=&quot;http://packages.qa.debian.org/p/pam-python.html&quot;&gt;pam-python&lt;/a&gt;
+package needed by libpam-mklocaluser, and the
+&lt;a href=&quot;http://packages.qa.debian.org/s/sssd.html&quot;&gt;sssd&lt;/a&gt; package
+passed NEW on Monday.  In addition, the
+&lt;a href=&quot;http://packages.qa.debian.org/libp/libpam-ccreds.html&quot;&gt;libpam-ccreds&lt;/a&gt;
+package we need is in experimental (version 10-4) since Saturday, and
+hopefully will be moved to unstable soon.&lt;/p&gt;
+
+&lt;p&gt;This collection of packages allow for two different setups for
+roaming laptops.  The traditional setup would be using libpam-ccreds,
+nscd and libpam-mklocaluser with LDAP or Kerberos authentication,
+which should work out of the box if the configuration changes proposed
+for nscd in &lt;a href=&quot;http://bugs.debian.org/485282&quot;&gt;BTS report
+#485282&lt;/a&gt; is implemented.  The alternative setup is to use sssd with
+libpam-mklocaluser to connect to LDAP or Kerberos and let sssd take
+care of the caching of passwords and group information.&lt;/p&gt;
+
+&lt;p&gt;I have so far been unable to get sssd to work with the LDAP server
+at the University, but suspect the issue is some SSL/GnuTLS related
+problem with the server certificate.  I plan to update the Debian
+package to version 1.2, which is scheduled for next week, and hope to
+find time to make sure the next release will include both the
+Debian/Ubuntu specific patches.  Upstream is friendly and responsive,
+and I am sure we will find a good solution.&lt;/p&gt;
+
+&lt;p&gt;The idea is to set up the roaming laptops to authenticate using
+LDAP or Kerberos and create a local user with home directory in /home/
+when a usre in LDAP logs in via KDM or GDM for the first time, and
+cache the password for offline checking, as well as caching group
+memberhips and other relevant LDAP information.  The
+libpam-mklocaluser package was created to make sure the local home
+directory is in /home/, instead of /site/server/directory/ which would
+be the home directory if pam_mkhomedir was used.  To avoid confusion
+with support requests and configuration, we do not want local laptops
+to have users in a path that is used for the same users home directory
+on the home directory servers.&lt;/p&gt;
+
+&lt;p&gt;One annoying problem with gdm is that it do not show the PAM
+message passed to the user from libpam-mklocaluser when the local user
+is created.  Instead gdm simply reject the login with some generic
+message.  The message is shown in kdm, ssh and login, so I guess it is
+a bug in gdm.  Have not investigated if there is some other message
+type that can be used instead to get gdm to also show the message.&lt;/p&gt;
+
+&lt;p&gt;If you want to help out with implementing this for Debian Edu,
+please contact us on debian-edu@lists.debian.org.&lt;/p&gt;

                <description>

-&lt;p&gt;There are two software projects that have had huge influence on the
-quality of free software, and I wanted to mention both in case someone
-do not yet know them.&lt;/p&gt;
-
-&lt;p&gt;The first one is &lt;a href=&quot;http://valgrind.org/&quot;&gt;valgrind&lt;/a&gt;, a
-tool to detect and expose errors in the memory handling of programs.
-It is easy to use, all one need to do is to run &#39;valgrind program&#39;,
-and it will report any problems on stdout.  It is even better if the
-program include debug information.  With debug information, it is able
-to report the source file name and line number where the problem
-occurs.  It can report things like &#39;reading past memory block in file
-X line N, the memory block was allocated in file Y, line M&#39;, and
-&#39;using uninitialised value in control logic&#39;.  This tool has made it
-trivial to investigate reproducible crash bugs in programs, and have
-reduced the number of this kind of bugs in free software a lot.
-
-&lt;p&gt;The second one is
-&lt;a href=&quot;http://en.wikipedia.org/wiki/Coverity&quot;&gt;Coverity&lt;/a&gt; which is
-a source code checker.  It is able to process the source of a program
-and find problems in the logic without running the program.  It
-started out as the Stanford Checker and became well known when it was
-used to find bugs in the Linux kernel.  It is now a commercial tool
-and the company behind it is running
-&lt;a href=&quot;http://www.scan.coverity.com/&quot;&gt;a community service&lt;/a&gt; for the
-free software community, where a lot of free software projects get
-their source checked for free.  Several thousand defects have been
-found and fixed so far.  It can find errors like &#39;lock L taken in file
-X line N is never released if exiting in line M&#39;, or &#39;the code in file
-Y lines O to P can never be executed&#39;.  The projects included in the
-community service project have managed to get rid of a lot of
-reliability problems thanks to Coverity.&lt;/p&gt;
-
-&lt;p&gt;I believe tools like this, that are able to automatically find
-errors in the source, are vital to improve the quality of software and
-make sure we can get rid of the crashing and failing software we are
-surrounded by today.&lt;/p&gt;
+&lt;p&gt;Since this evening, parallel booting is the default in
+Debian/unstable for machines using dependency based boot sequencing.
+Apparently the testing of concurrent booting has been wider than
+expected, if I am to believe the
+&lt;a href=&quot;http://lists.debian.org/debian-devel/2010/05/msg00122.html&quot;&gt;input
+on debian-devel@&lt;/a&gt;, and I concluded a few days ago to move forward
+with the feature this weekend, to give us some time to detect any
+remaining problems before Squeeze is frozen.  If serious problems are
+detected, it is simple to change the default back to sequential boot.
+The upload of the new sysvinit package also activate a new upstream
+version.&lt;/p&gt;
+
+More information about
+&lt;a href=&quot;http://wiki.debian.org/LSBInitScripts/DependencyBasedBoot&quot;&gt;dependency
+based boot sequencing&lt;/a&gt; is available from the Debian wiki.  It is
+currently possible to disable parallel booting when one run into
+problems caused by it, by adding this line to /etc/default/rcS:&lt;/p&gt;
+
+&lt;blockquote&gt;&lt;pre&gt;
+CONCURRENCY=none
+&lt;/pre&gt;&lt;/blockquote&gt;
+
+&lt;p&gt;If you report any problems with dependencies in init.d scripts to
+the BTS, please usertag the report to get it to show up at
+&lt;a href=&quot;http://bugs.debian.org/cgi-bin/pkgreport.cgi?users=initscripts-ng-devel@lists.alioth.debian.org&quot;&gt;the
+list of usertagged bugs related to this&lt;/a&gt;.&lt;/p&gt;

-&lt;p&gt;Julien Blache
-&lt;a href=&quot;http://blog.technologeek.org/2009/04/12/214&quot;&gt;claim that no
-patch is better than a useless patch&lt;/a&gt;.  I completely disagree, as a
-patch allow one to discuss a concrete and proposed solution, and also
-prove that the issue at hand is important enough for someone to spent
-time on fixing it.  No patch do not provide any of these positive
-properties.&lt;/p&gt;
+&lt;p&gt;In the recent Debian Edu versions, the
+&lt;a href=&quot;http://wiki.debian.org/DebianEdu/HowTo/SiteSummary&quot;&gt;sitesummary
+system&lt;/a&gt; is used to keep track of the machines in the school
+network.  Each machine will automatically report its status to the
+central server after boot and once per night.  The network setup is
+also reported, and using this information it is possible to get the
+MAC address of all network interfaces in the machines.  This is useful
+to update the DHCP configuration.&lt;/p&gt;
+
+&lt;p&gt;To give some idea how to use sitesummary, here is a one-liner to
+ist all MAC addresses of all machines reporting to sitesummary.  Run
+this on the collector host:&lt;/p&gt;
+
+&lt;blockquote&gt;&lt;pre&gt;
+perl -MSiteSummary -e &#39;for_all_hosts(sub { print join(&quot; &quot;, get_macaddresses(shift)), &quot;\n&quot;; });&#39;
+&lt;/pre&gt;&lt;/blockquote&gt;
+
+&lt;p&gt;This will list all MAC addresses assosiated with all machine, one
+line per machine and with space between the MAC addresses.&lt;/p&gt;
+
+&lt;p&gt;To allow system administrators easier job at adding static DHCP
+addresses for hosts, it would be possible to extend this to fetch
+machine information from sitesummary and update the DHCP and DNS
+tables in LDAP using this information.  Such tool is unfortunately not
+written yet.&lt;/p&gt;

                <description>
                <description>

-&lt;p&gt;Slashdot melder at EU-parlamentet har vedtatt
-&lt;a href=&quot;http://www.europarl.europa.eu/news/expert/infopress_page/058-54192-111-04-17-909-20090422IPR54191-21-04-2009-2009-false/default_en.htm&quot;&gt;å
-øke vernetiden for musikkopptak fra 50 til 70 år&lt;/a&gt;, og dermed rane
-fellesskapet for 20 år med musikk som ville vært tilgjengelig uten
-bruksbegresninger.  Mon tro hvor mye musikk som vil gå tapt pga. at
-ingen tar vare på den (opphavsrettsinnehaver er forsvunnet), mens
-ingen andre har lov til å kopiere og distribuere den.  Mon tro hvor
-mange musikkstykker som ikke kan brukes uten bruksbegresninger av
-folket, som skulle falt i det fri men som i stedet forblir under
-rettighetshavers monopol.  Opphavsrettslovgivingen blir mer og mer
-urimelig.  Tenke seg til at vernetiden startet i USA med 7 år og
-mulighet for forlengelse med 7 år.  Nå er den 95 år der, og en stor
-mengde verk blir foreldreløse og umulig å få tak i.  Har ikke lykkes
-med å finne ut hvor lang opphavsretten var i utgangspunktet i Norge.
-I dag er den 70 år.&lt;/p&gt;
-
-&lt;p&gt;Jeg er glad det finnes &lt;a href=&quot;http://www.jamendo.com/&quot;&gt;så mye
-musikk tilgjengelig uten bruksbegresninger&lt;/a&gt; at en kan klare seg
-uten musikk med bruksbegresninger.&lt;/p&gt;
+&lt;p&gt;The last few days a new boot system called
+&lt;a href=&quot;http://www.freedesktop.org/wiki/Software/systemd&quot;&gt;systemd&lt;/a&gt;
+has been
+&lt;a href=&quot;http://0pointer.de/blog/projects/systemd.html&quot;&gt;introduced&lt;/a&gt;
+
+to the free software world.  I have not yet had time to play around
+with it, but it seem to be a very interesting alternative to
+&lt;a href=&quot;http://upstart.ubuntu.com/&quot;&gt;upstart&lt;/a&gt;, and might prove to be
+a good alternative for Debian when we are able to switch to an event
+based boot system.  Tollef is
+&lt;a href=&quot;http://bugs.debian.org/580814&quot;&gt;in the process&lt;/a&gt; of getting
+systemd into Debian, and I look forward to seeing how well it work.  I
+like the fact that systemd handles init.d scripts with dependency
+information natively, allowing them to run in parallel where upstart
+at the moment do not.&lt;/p&gt;
+
+&lt;p&gt;Unfortunately do systemd have the same problem as upstart regarding
+platform support.  It only work on recent Linux kernels, and also need
+some new kernel features enabled to function properly.  This means
+kFreeBSD and Hurd ports of Debian will need a port or a different boot
+system.  Not sure how that will be handled if systemd proves to be the
+way forward.&lt;/p&gt;
+
+&lt;p&gt;In the mean time, based on the
+&lt;a href=&quot;http://lists.debian.org/debian-devel/2010/05/msg00122.html&quot;&gt;input
+on debian-devel@&lt;/a&gt; regarding parallel booting in Debian, I have
+decided to enable full parallel booting as the default in Debian as
+soon as possible (probably this weekend or early next week), to see if
+there are any remaining serious bugs in the init.d dependencies.  A
+new version of the sysvinit package implementing this change is
+already in experimental.  If all go well, Squeeze will be released
+with parallel booting enabled by default.&lt;/p&gt;

                <description>

-&lt;p&gt;Dagens nyhet er at omsetningen til Microsoft for første gang er
-synkende.  Ikke spesielt uventet med den generelle nedgangen i
-økonomien som vi ser verden over.  Det fikk meg dog til å tenke på en
-ting fra noen år tilbake.&lt;/p&gt;
-
-&lt;p&gt;Da jeg besøkte en kamerat i Beijing sommeren 2000, ble jeg fortalt
-at påstanden til Microsoft om at de brakte inn enorme pengesummer til
-USA nok var litt overdrevet, da de fleste inntektene fra lisenssalg
-rundt om i verden ble kanalisert inn til skatteparadiset
-&lt;a href=&quot;http://en.wikipedia.org/wiki/Cayman_Islands&quot;&gt;Cayman
-Island&lt;/a&gt;.  Jeg har aldri lykkes med å få bekreftet dette påstanden,
-men tok i dag en titt på hvilke selskaper som eier de norske delene av
-Microsoft som jeg kjenner til, dvs.
-&lt;a href=&quot;http://www.proff.no/proff/search/companyRoles.c?freeText=microsoft&amp;bc=0&amp;c=Z001YP4Y&amp;org=957485030&quot;&gt;Microsoft
-Norge AS&lt;/a&gt; og
-&lt;a href=&quot;http://www.proff.no/proff/search/companyRoles.c?freeText=fast&amp;bc=348&amp;c=Z0HR5KDT&amp;org=979158831&quot;&gt;FAST,
-A Microsoft Subsidiary&lt;/a&gt; (tidligere FAST Search &amp; Transfer ASA).&lt;/p&gt;
-
-&lt;p&gt;Førstnevnte er eid av &quot;Microsoft International Holdings Spain
-S.R.L.&quot;, mens sistnevnte i følge Wikipedia nå eies av
-Microsoft-underselskapet &quot;MACS Holdings Limited&quot;.  Jeg har ikke klart
-å finne mer informasjon om noen av disse.  Mon tro om noen av dem
-sender pengene til Cayman Island?  Finner det jeg tror er
-&lt;a href=&quot;http://www.informacion-empresas.com/Empresa_MICROSOFT-INTERNATIONAL-HOLDINGS-SPAIN.html&quot;&gt;informasjon
-om spaniaselskapet på spansk&lt;/a&gt;, men jeg kan ikke lese spansk. :(&lt;/p&gt;
+&lt;p&gt;These days, the init.d script dependencies in Squeeze are quite
+complete, so complete that it is actually possible to run all the
+init.d scripts in parallell based on these dependencies.  If you want
+to test your Squeeze system, make sure
+&lt;a href=&quot;http://wiki.debian.org/LSBInitScripts/DependencyBasedBoot&quot;&gt;dependency
+based boot sequencing&lt;/a&gt; is enabled, and add this line to
+/etc/default/rcS:&lt;/p&gt;
+
+&lt;blockquote&gt;&lt;pre&gt;
+CONCURRENCY=makefile
+&lt;/pre&gt;&lt;/blockquote&gt;
+
+&lt;p&gt;That is it.  It will cause sysv-rc to use the startpar tool to run
+scripts in parallel using the dependency information stored in
+/etc/init.d/.depend.boot, /etc/init.d/.depend.start and
+/etc/init.d/.depend.stop to order the scripts.  Startpar is configured
+to try to start the kdm and gdm scripts as early as possible, and will
+start the facilities required by kdm or gdm as early as possible to
+make this happen.&lt;/p&gt;
+
+&lt;p&gt;Give it a try, and see if you like the result.  If some services
+fail to start properly, it is most likely because they have incomplete
+init.d script dependencies in their startup script (or some of their
+dependent scripts have incomplete dependencies).  Report bugs and get
+the package maintainers to fix it. :)&lt;/p&gt;
+
+&lt;p&gt;Running scripts in parallel could be the default in Debian when we
+manage to get the init.d script dependencies complete and correct.  I
+expect we will get there in Squeeze+1, if we get manage to test and
+fix the remaining issues.&lt;/p&gt;
+
+&lt;p&gt;If you report any problems with dependencies in init.d scripts to
+the BTS, please usertag the report to get it to show up at
+&lt;a href=&quot;http://bugs.debian.org/cgi-bin/pkgreport.cgi?users=initscripts-ng-devel@lists.alioth.debian.org&quot;&gt;the
+list of usertagged bugs related to this&lt;/a&gt;.&lt;/p&gt;
