The design for handling this +in <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a>, is +to update the automount rules in LDAP and let the automount daemon on +the clients take care of the rest. I was reminded about the need to +document this better when one of the customers of +<a href="http://www.slxdrift.no/">Skolelinux Drift AS</a>, where I am +on the board of directors, asked about how to do this. The steps to +get this working are the following:</p> + +<p><ol> + +<li>Add new storage server in DNS. I use nas-server.intern as the +example host here.</li> + +<li>Add automoun LDAP information about this server in LDAP, to allow +all clients to automatically mount it on reqeust.</li> + +<li>Add the relevant entries in tjener.intern:/etc/fstab, because +tjener.intern do not use automount to avoid mounting loops.</li> + +</ol></p> + +<p>DNS entries are added in GOsa², and not described here. Follow the +<a href="https://wiki.debian.org/DebianEdu/Documentation/Wheezy/GettingStarted">instructions +in the manual</a> (Machine Management with GOsa² in section Getting +started).</p> + +<p>Ensure that the NFS export points on the server are exported to the +relevant subnets or machines:</p> + +<p><blockquote><pre> +root@tjener:~# showmount -e nas-server +Export list for nas-server: +/storage 10.0.0.0/8 +root@tjener:~# +</pre></blockquote></p> + +<p>Here everything on the backbone network is granted access to the +/storage export. With NFSv3 it is slightly better to limit it to +netgroup membership or single IP addresses to have some limits on the +NFS access.</p> + +<p>The next step is to update LDAP. This can not be done using GOsa², +because it lack a module for automount. Instead, use ldapvi and add +the required LDAP objects using an editor.</p> + +<p><blockquote><pre> +ldapvi --ldap-conf -ZD '(cn=admin)' -b ou=automount,dc=skole,dc=skolelinux,dc=no +</pre></blockquote></p> + +<p>When the editor show up, add the following LDAP objects at the +bottom of the document. The "/&" part in the last LDAP object is a +wild card matching everything the nas-server exports, removing the +need to list individual mount points in LDAP.</p> + +<p><blockquote><pre> +add cn=nas-server,ou=auto.skole,ou=automount,dc=skole,dc=skolelinux,dc=no +objectClass: automount +cn: nas-server +automountInformation: -fstype=autofs --timeout=60 ldap:ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no + +add ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no +objectClass: top +objectClass: automountMap +ou: auto.nas-server + +add cn=/,ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no +objectClass: automount +cn: / +automountInformation: -fstype=nfs,tcp,rsize=32768,wsize=32768,rw,intr,hard,nodev,nosuid,noatime nas-server.intern:/& +</pre></blockquote></p> + +<p>The last step to remember is to mount the relevant mount points in +tjener.intern by adding them to /etc/fstab, creating the mount +directories using mkdir and running "mount -a" to mount them.</p> + +<p>When this is done, your users should be able to access the files on +the storage server directly by just visiting the +/tjener/nas-server/storage/ directory using any application on any +workstation, LTSP client or LTSP server.</p> + + + + + Hvordan bør RFC 822-formattert epost lagres i en NOARK5-database? + http://people.skolelinux.org/pere/blog/Hvordan_b_r_RFC_822_formattert_epost_lagres_i_en_NOARK5_database_.html + http://people.skolelinux.org/pere/blog/Hvordan_b_r_RFC_822_formattert_epost_lagres_i_en_NOARK5_database_.html + Fri, 7 Mar 2014 15:20:00 +0100 + <p>For noen uker siden ble NXCs fri programvarelisenserte +NOARK5-løsning +<a href="http://www.nuug.no/aktiviteter/20140211-noark/">presentert hos +NUUG</a> (video +<a href="https://www.youtube.com/watch?v=JCb_dNS3MHQ">på youtube +foreløbig</a>), og det fikk meg til å titte litt mer på NOARK5, +standarden for arkivhåndtering i det offentlige Norge. Jeg lurer på +om denne kjernen kan være nyttig i et par av mine prosjekter, og for ett +av dem er det mest aktuelt å lagre epost. Jeg klarte ikke finne noen +anbefaling om hvordan RFC 822-formattert epost (aka Internett-epost) +burde lagres i NOARK5, selv om jeg vet at noen arkiver tar +PDF-utskrift av eposten med sitt epostprogram og så arkiverer PDF-en +(eller enda værre, tar papirutskrift og lagrer bildet av eposten som +PDF i arkivet).</p> + +<p>Det er ikke så mange formater som er akseptert av riksarkivet til +langtidsoppbevaring av offentlige arkiver, og PDF og XML er de mest +aktuelle i så måte. Det slo meg at det måtte da finnes en eller annen +egnet XML-representasjon og at det kanskje var enighet om hvilken som +burde brukes, så jeg tok mot til meg og spurte +<a href="http://samdok.com/">SAMDOK</a>, en gruppe tilknyttet +arkivverket som ser ut til å jobbe med NOARK-samhandling, om de hadde +noen anbefalinger: + +<p><blockquote> +<p>Hei.</p> + +<p>Usikker på om dette er riktig forum å ta opp mitt spørsmål, men jeg +lurer på om det er definert en anbefaling om hvordan RFC +822-formatterte epost (aka vanlig Internet-epost) bør lages håndteres +i NOARK5, slik at en bevarer all informasjon i eposten +(f.eks. Received-linjer). Finnes det en anbefalt XML-mapping ala den +som beskrives på +&lt;URL: <a href="https://www.informit.com/articles/article.aspx?p=32074">https://www.informit.com/articles/article.aspx?p=32074</a> &gt;? Mitt +mål er at det skal være mulig å lagre eposten i en NOARK5-kjerne og +kunne få ut en identisk formattert kopi av opprinnelig epost ved +behov.</p> +</blockquote></p> + +<p>Postmottaker hos SAMDOK mente spørsmålet heller burde stilles +direkte til riksarkivet, og jeg fikk i dag svar derfra formulert av +seniorrådgiver Geir Ivar Tungesvik:</p> + +<p><blockquote> +<p>Riksarkivet har ingen anbefalinger når det gjelder konvertering fra +e-post til XML. Det står arkivskaper fritt å eventuelt definere/bruke +eget format. Inklusive da - som det spørres om - et format der det er +mulig å re-etablere e-post format ut fra XML-en. XML (e-post) +dokumenter må være referert i arkivstrukturen, og det må vedlegges et +gyldig XML skjema (.xsd) for XML-filene. Arkivskaper står altså fritt +til å gjøre hva de vil, bare det dokumenteres og det kan dannes et +utrekk ved avlevering til depot.</p> + +<p>De obligatoriske kravene i Noark 5 standarden må altså oppfylles - +etter dialog med Riksarkivet i forbindelse med godkjenning. For +offentlige arkiv er det særlig viktig med filene loependeJournal.xml +og offentligJournal.xml. Private arkiv som vil forholde seg til Noark +5 standarden er selvsagt frie til å bruke det som er relevant for dem +av obligatoriske krav.</p> +</blockquote></p> + +<p>Det ser dermed ut for meg som om det er et lite behov for å +standardisere XML-lagring av RFC-822-formatterte meldinger.

This follow up on the +<a href="https://teythoon.cryptobitch.de//categories/gsoc.html">great +Google Summer of Code work</a> done last summer by Justus Winter to +get Debian on Hurd working more like Debian on Linux. To get started, +I downloaded a prebuilt hard disk image from +<a href="http://ftp.debian-ports.org/debian-cd/hurd-i386/current/debian-hurd.img.tar.gz">http://ftp.debian-ports.org/debian-cd/hurd-i386/current/debian-hurd.img.tar.gz</a>, +and started it using virt-manager.</p> + +<p>The first think I had to do after logging in (root without any +password) was to get the network operational. I followed +<a href="https://www.debian.org/ports/hurd/hurd-install">the +instructions on the Debian GNU/Hurd ports page</a> and ran these +commands as root to get the machine to accept a IP address from the +kvm internal DHCP server:</p> + +<p><blockquote><pre> +settrans -fgap /dev/netdde /hurd/netdde +kill $(ps -ef|awk '/[p]finet/ { print $2}') +kill $(ps -ef|awk '/[d]evnode/ { print $2}') +dhclient /dev/eth0 +</pre></blockquote></p> + +<p>After this, the machine had internet connectivity, and I could +upgrade it and install the sysvinit packages from experimental and +enable it as the default boot system in Hurd.</p> + +<p>But before I did that, I set a password on the root user, as ssh is +running on the machine it for ssh login to work a password need to be +set. Also, note that a bug somewhere in openssh on Hurd block +compression from working. Remember to turn that off on the client +side.</p> + +<p>Run these commands as root to upgrade and test the new sysvinit +stuff:</p> + +<p><blockquote><pre> +cat > /etc/apt/sources.list.d/experimental.list &lt;&lt;EOF +deb http://http.debian.net/debian/ experimental main +EOF +apt-get update +apt-get dist-upgrade +apt-get install -t experimental initscripts sysv-rc sysvinit \ + sysvinit-core sysvinit-utils +update-alternatives --config runsystem +</pre></blockquote></p> + +<p>To reboot after switching boot system, you have to use +<tt>reboot-hurd</tt> instead of just <tt>reboot</tt>, as there is not +yet a sysvinit process able to receive the signals from the normal +'reboot' command. After switching to sysvinit as the boot system, +upgrading every package and rebooting, the network come up with DHCP +after boot as it should, and the settrans/pkill hack mentioned at the +start is no longer needed. But for some strange reason, there are no +longer any login prompt in the virtual console, so I logged in using +ssh instead. + +<p>Note that there are some race conditions in Hurd making the boot +fail some times. No idea what the cause is, but hope the Hurd porters +figure it out. At least Justus said on IRC (#debian-hurd on +irc.debian.org) that they are aware of the problem. A way to reduce +the impact is to upgrade to the Hurd packages built by Justus by +adding this repository to the machine:</p> + +<p><blockquote><pre> +cat > /etc/apt/sources.list.d/hurd-ci.list &lt;&lt;EOF +deb http://darnassus.sceen.net/~teythoon/hurd-ci/ sid main +EOF +</pre></blockquote></p> + +<p>At the moment the prebuilt virtual machine get some packages from +http://ftp.debian-ports.org/debian, because some of the packages in +unstable do not yet include the required patches that are lingering in +BTS. This is the completely list of "unofficial" packages installed:</p> + +<p><blockquote><pre> +# aptitude search '?narrow(?version(CURRENT),?origin(Debian Ports))' +i emacs - GNU Emacs editor (metapackage) +i gdb - GNU Debugger +i hurd-recommended - Miscellaneous translators +i isc-dhcp-client - ISC DHCP client +i isc-dhcp-common - common files used by all the isc-dhcp* packages +i libc-bin - Embedded GNU C Library: Binaries +i libc-dev-bin - Embedded GNU C Library: Development binaries +i libc0.3 - Embedded GNU C Library: Shared libraries +i A libc0.3-dbg - Embedded GNU C Library: detached debugging symbols +i libc0.3-dev - Embedded GNU C Library: Development Libraries and Hea +i multiarch-support - Transitional package to ensure multiarch compatibilit +i A x11-common - X Window System (X.Org) infrastructure +i xorg - X.Org X Window System +i A xserver-xorg - X.Org X server +i A xserver-xorg-input-all - X.Org X server -- input driver metapackage +# +</pre></blockquote></p> + +<p>All in all, testing hurd has been an interesting experience. :) +X.org did not work out of the box and I never took the time to follow +the porters instructions to fix it.

The most -know ones are the killer drones used by some government to murder -people they do not like without giving them the chance of a fair -trial, but the technology have many good uses too, from mapping and -forest maintenance to photography and search and rescue. I am sure it -is just a question of time before "bad drones" are in the hands of -private enterprises and not only state criminals but petty criminals -too. The drone technology is very useful and very dangerous. To have -some control over the use of drones, I agree with Daniel Suarez in his -TED talk -"<a href="https://archive.org/details/DanielSuarez_2013G">The kill -decision shouldn't belong to a robot</a>", where he suggested this -little gem to keep the good while limiting the bad use of drones:</p> - -<blockquote> - -<p>Each robot and drone should have a cryptographically signed -I.D. burned in at the factory that can be used to track its movement -through public spaces. We have license plates on cars, tail numbers on -aircraft. This is no different. And every citizen should be able to -download an app that shows the population of drones and autonomous -vehicles moving through public spaces around them, both right now and -historically. And civic leaders should deploy sensors and civic drones -to detect rogue drones, and instead of sending killer drones of their -own up to shoot them down, they should notify humans to their -presence. And in certain very high-security areas, perhaps civic -drones would snare them and drag them off to a bomb disposal facility.</p> - -<p>But notice, this is more an immune system than a weapons system. It -would allow us to avail ourselves of the use of autonomous vehicles -and drones while still preserving our open, civil society.</p> - -</blockquote> - -<p>The key is that <em>every citizen</em> should be able to read the -radio beacons sent from the drones in the area, to be able to check -both the government and others use of drones. For such control to be -effective, everyone must be able to do it. What should such beacon -contain? At least formal owner, purpose, contact information and GPS -location. Probably also the origin and target position of the current -flight. And perhaps some registration number to be able to look up -the drone in a central database tracking their movement. Robots -should not have privacy. It is people who need privacy.</p> + A fist full of non-anonymous Bitcoins + http://people.skolelinux.org/pere/blog/A_fist_full_of_non_anonymous_Bitcoins.html + http://people.skolelinux.org/pere/blog/A_fist_full_of_non_anonymous_Bitcoins.html + Wed, 29 Jan 2014 14:10:00 +0100 + <p>Bitcoin is a incredible use of peer to peer communication and +encryption, allowing direct and immediate money transfer without any +central control. It is sometimes claimed to be ideal for illegal +activity, which I believe is quite a long way from the truth. At least +I would not conduct illegal money transfers using a system where the +details of every transaction are kept forever. This point is +investigated in +<a href="https://www.usenix.org/publications/login">USENIX ;login:</a> +from December 2013, in the article +"<a href="https://www.usenix.org/system/files/login/articles/03_meiklejohn-online.pdf">A +Fistful of Bitcoins - Characterizing Payments Among Men with No +Names</a>" by Sarah Meiklejohn, Marjori Pomarole,Grant Jordan, Kirill +Levchenko, Damon McCoy, Geoffrey M. Voelker, and Stefan Savage. They +analyse the transaction log in the Bitcoin system, using it to find +addresses belong to individuals and organisations and follow the flow +of money from both Bitcoin theft and trades on Silk Road to where the +money end up. This is how they wrap up their article:</p> + +<p><blockquote> +<p>"To demonstrate the usefulness of this type of analysis, we turned +our attention to criminal activity. In the Bitcoin economy, criminal +activity can appear in a number of forms, such as dealing drugs on +Silk Road or simply stealing someone else’s bitcoins. We followed the +flow of bitcoins out of Silk Road (in particular, from one notorious +address) and from a number of highly publicized thefts to see whether +we could track the bitcoins to known services. Although some of the +thieves attempted to use sophisticated mixing techniques (or possibly +mix services) to obscure the flow of bitcoins, for the most part +tracking the bitcoins was quite straightforward, and we ultimately saw +large quantities of bitcoins flow to a variety of exchanges directly +from the point of theft (or the withdrawal from Silk Road).</p> + +<p>As acknowledged above, following stolen bitcoins to the point at +which they are deposited into an exchange does not in itself identify +the thief; however, it does enable further de-anonymization in the +case in which certain agencies can determine (through, for example, +subpoena power) the real-world owner of the account into which the +stolen bitcoins were deposited. Because such exchanges seem to serve +as chokepoints into and out of the Bitcoin economy (i.e., there are +few alternative ways to cash out), we conclude that using Bitcoin for +money laundering or other illicit purposes does not (at least at +present) seem to be particularly attractive."</p> +</blockquote><p> + +<p>These researches are not the first to analyse the Bitcoin +transaction log. The 2011 paper +"<a href="http://arxiv.org/abs/1107.4524">An Analysis of Anonymity in +the Bitcoin System</A>" by Fergal Reid and Martin Harrigan is +summarized like this:</p> + +<p><blockquote> +"Anonymity in Bitcoin, a peer-to-peer electronic currency system, is a +complicated issue. Within the system, users are identified by +public-keys only. An attacker wishing to de-anonymize its users will +attempt to construct the one-to-many mapping between users and +public-keys and associate information external to the system with the +users. Bitcoin tries to prevent this attack by storing the mapping of +a user to his or her public-keys on that user's node only and by +allowing each user to generate as many public-keys as required. In +this chapter we consider the topological structure of two networks +derived from Bitcoin's public transaction history. We show that the +two networks have a non-trivial topological structure, provide +complementary views of the Bitcoin system and have implications for +anonymity. We combine these structures with external information and +techniques such as context discovery and flow analysis to investigate +an alleged theft of Bitcoins, which, at the time of the theft, had a +market value of approximately half a million U.S. dollars." +</blockquote></p> + +<p>I hope these references can help kill the urban myth that Bitcoin +is anonymous. It isn't really a good fit for illegal activites. Use +cash if you need to stay anonymous, at least until regular DNA +sampling of notes and coins become the norm. :)</p> + +<p>As usual, if you use Bitcoin and want to show your support of my +activities, please send Bitcoin donations to my address +<b><a href="bitcoin:15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&label=PetterReinholdtsenBlog">15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b</a></b>.</p> - Lets make a wireless community network in Oslo! - http://people.skolelinux.org/pere/blog/Lets_make_a_wireless_community_network_in_Oslo_.html - http://people.skolelinux.org/pere/blog/Lets_make_a_wireless_community_network_in_Oslo_.html - Wed, 13 Nov 2013 21:00:00 +0100 - <p>Today NUUG and Hackeriet announced -<a href="http://www.nuug.no/news/Bli_med___bygge_dugnadsnett_for_alle_i_Oslo.shtml">our -plans to join forces and create a wireless community network in -Oslo</a>.

It can detect a lot of different problems, and is very +useful to find memory and locking bugs in the error handling part of +the source. The company behind it provide +<a href="https://scan.coverity.com/">check of free software projects as +a community service</a>, and many hundred free software projects are +already checked. A few days ago I decided to have a closer look at +the Coverity system, and discovered that the +<a href="http://www.gnu.org/software/gnash/">gnash</a> and +<a href="http://sourceforge.net/projects/ipmitool/">ipmitool</a> +projects I am involved with was already registered. But these are +fairly big, and I would also like to have a small and easy project to +check, and decided to <a href="http://scan.coverity.com/projects/1179">request +checking of the chrpath project</a>. It was +added to the checker and discovered seven potential defects. Six of +these were real, mostly resource "leak" when the program detected an +error. Nothing serious, as the resources would be released a fraction +of a second later when the program exited because of the error, but it +is nice to do it right in case the source of the program some time in +the future end up in a library.

A small snag was the fact that the -<tt>opkg install kmod-batman-adv</tt> command did not work as it -should. The batman-adv kernel module would fail to load because its -dependency crc16 was not already loaded. I -<a href="https://dev.openwrt.org/ticket/14452">reported the bug</a> to -the openwrt project and hope it will be fixed soon.

After overcoming some minor (but still very annoying) glitches +in the installer, I got a fully functional, working school network, +without the month-long hassle I experienced when setting all that up +from scratch in earlier years. And above that, it rocked - I didn't +have any real hardware at hand, because the school was just founded +and has no money whatsoever, so I installed a combined server (main +server, terminal services and workstation) in a VM on my personal +notebook, bridging the LTSP network interface to the ethernet port, +and then PXE-booted the Windows notebooks that were lying around from +it. I could use 8 clients without any performance issues, by using a +tiny little VM on a tiny little notebook. I think that's enough to say +that it rocks!</p> + +<p>Secondly, there are marketing reasons. Life's bad, and so no +politician will ever permit a setup described as "Debian, an universal +operating system, with some really cool educational tools" while they +will be jsut fine with "Skolelinux, a single-purpose solution for your +school network", even if both turn out to be the very same thing (yes, +this is unfair towards the Skolelinux project, and must not be taken +too seriously - you get the idea, anyway).</p> -<p>The mesh node is now operational. I have yet to test its range, -but I hope it is good. I have not yet tested the TP-Link 3600 box -still wrapped up in plastic.</p> +<p><strong>What do you see as the disadvantages of Skolelinux / Debian +Edu?</strong></p> + +<p>I have not been involved with Skolelinux long enough to really +answer this question in a fair way. Thus, please allow me to put it in +other words: "What do you expect from Skolelinux to keep liking it?" I +can list a few points about that:</p> + +<ul> + + <li>always strive to get all things integrated into Debian upstream + <li>be open to discussion about changes and the like, even with newcomers + <li>be helpful at being helpful ;) + +</ul> + +<p>I'm really sorry I cannot say much more about that :(!</p> + +<p><strong>Which free software do you use daily?</strong></p> + +<p>First of all, all software I use is free and open. I have abandoned +all non-free software (except for firmware on my darned phone) this +year.</p> + +<p>I run Debian GNU/Linux on all PC systems I use. On that, I mostly +run text tools. I use +<a href="https://www.mirbsd.org/mksh.htm">mksh</a> as shell, +<a href="https://www.mirbsd.org/jupp.htm">jupp</a> as very advanced +text editor (I even got the developer to help me write a script/macro +based full-featured student management software with the two), +<a href="http://mcabber.com/">mcabber</a> for XMPP and +<a href="http://www.irssi.org/">irssi</a> for IRC. For that overly +coloured world called the WWW, I use +<a href="https://www.mozilla.org/en-US/firefox/new/">Iceweasel +(Firefox)</a>. Oh, and <a href="http://www.mutt.org/">mutt</a> for +e-mail.</p> + +<p>However, while I am personally aware of the fact that text tools +are more efficient and powerful than anything else, I also use (or at +least operate) some tools that are suitable to bring open source to +kids. One of these things is <a href="http://jappix.org/">Jappix</a>, +which I already introduced to some kids even before they got aware of +Facebook, making them see for themselves that they do not need +Facebook now ;).</p> + +<p><strong>Which strategy do you believe is the right one to use to +get schools to use free software?</strong></p> + +<p>Well, that's a two-sided thing. One side is what I believe, and one +side is what I have experienced.</p> + +<p>I believe that the right strategy is showing them the benefits. But +that won't work out as long as the acceptance of free alternatives +grows globally. What I mean is that if all the kids are almost forced +to use Windows, Facebook, Skype, you name it at home, they will not +see why they would want to use alternatives at school. I have seen +students take seat in front of a fully-functional, modern Debian +desktop that could do anything their Windows at home could do, and +they jsut refused to use it because "Linux sucks". It is something +that makes the council of our city spend around 600000 € to buy +software - not including hardware, mind you - for operating school +networks, and for installing a system that, as has been proved, does +not work. For those of you readers who are good at maths, have you +already found out how many lives could have been saved with that money +if we had instead used it to bring education to parts of the world +that need it? I have, and found it to be nothing less dramatic than +plain criminal.</p> + +<p>That said, the only feasible way appears to be the bottom up +method. We have to bring free software to kids and parents. I have +founded an association named +<a href="https://www.teckids.org">Teckids</a> here in Germany that does +just that. We organise several events for kids and adolescents in the +area of free and open source software, for example the +<a href="http://kids.froscon.org">FrogLabs</a>, which share staff with +Teckids and are the youth programme of +<a href="http://www.froscon.org">the Free and Open Source Software +Conference (FrOSCon)</a>. We do a lot more than most other conferences +- this year, we first offered the FrogLabs as a holiday camp for kids +aged 10 to 16. It was a huge success, with approx. 30 kids taking part +and learning with and about free software through a whole weekend. All +of us had a lot of fun, and the results were really exciting.</p> + +<p>Apart from that, we are preparing a campaign that is supposed to bring +the message of free alternatives to stuff kids use every day to them and +their parents, e.g. the use of Jabber / Jappix instead of Facebook and +Skype. To make that possible, we are planning to get together a team of +clever kids who understand very well what their peers need and can bring +it across to them. So we will have a peer-driven network of adolescents +who teach each other and collect feedback from the community of minors. +We then take that feedback and our own experience to work closely with +open source projects, such as Skolelinux or Jappix, at improving their +software in a way that makes it more and more attractive for the target +group. At least I hope that we will have good cooperation with +Skolelinux in the future ;)!</p> + +<p>So in conclusion, what I believe is that, if it weren't for the world +being so bad, it should be very clear to the political decision makers +that the only way to go nowadays is free software for various reasons, +but I have learnt that the only way that seems to work is bottom up.</p> + +<!-- + +> * Who should be interviewed with this questions in the future? + +That's probably the hardest question of them all, as I do not know the +community. However, I would be willing to do the following: + + <li>Run an interview with a German headteacher who is very open to + free software, and also prefers it, but cannot really use it because + of the decision makers above; + <li>Run interviews with some kids, both with and without previous + knowledge about free software + +If that is wanted, just let me know ;). + +--> - Debian init.d boot script example for rsyslog - http://people.skolelinux.org/pere/blog/Debian_init_d_boot_script_example_for_rsyslog.html - http://people.skolelinux.org/pere/blog/Debian_init_d_boot_script_example_for_rsyslog.html - Sat, 2 Nov 2013 22:40:00 +0100 - <p>If one of the points of switching to a new init system in Debian is -<a href="http://thomas.goirand.fr/blog/?p=147">to get rid of huge -init.d scripts</a>, I doubt we need to switch away from sysvinit and -init.d scripts at all.
