  33 <p>It is strange to watch how a bug in Debian causing KDM to fail to
  34 start at boot when an NVidia video card is used is handled.  The
  35 problem seem to be that the nvidia X.org driver uses a long time to
  36 initialize, and this duration is longer than kdm is configured to
  37 wait.</p>
  38
  39 <p>I came across two bugs related to this issue,
  40 <a href="http://bugs.debian.org/583312">#583312</a> initially filed
  41 against initscripts and passed on to nvidia-glx when it became obvious
  42 that the nvidia drivers were involved, and
  43 <a href="http://bugs.debian.org/524751">#524751</a> initially filed against
  44 kdm and passed on to src:nvidia-graphics-drivers for unknown reasons.</p>
  45
  46 <p>To me, it seem that no-one is interested in actually solving the
  47 problem nvidia video card owners experience and make sure the Debian
  48 distribution work out of the box for these users.  The nvidia driver
  49 maintainers expect kdm to be set up to wait longer, while kdm expect
  50 the nvidia driver maintainers to fix the driver to start faster, and
  51 while they wait for each other I guess the users end up switching to a
  52 distribution that work for them.  I have no idea what the solution is,
  53 but I am pretty sure that waiting for each other is not it.</p>
  54
  55 <p>I wonder why we end up handling bugs this way.</p>

 107 <p>When using sitesummary at a site to track machines, it is possible
 108 to get a list of the machine types in use thanks to the DMI
 109 information extracted from each machine.  The script to do so is
 110 included in the sitesummary package, and here is example output from
 111 the Skolelinux build servers:</p>
 112
 113 <blockquote><pre>
 114 maintainer:~# /usr/lib/sitesummary/hardware-model-summary
 115   vendor                    count
 116   Dell Computer Corporation     1
 117     PowerEdge 1750              1
 118   IBM                           1
 119     eserver xSeries 345 -[8670M1X]-     1
 120   Intel                         2
 121   [no-dmi-info]                 3
 122 maintainer:~#
 123 </pre></blockquote>
 124
 125 <p>The quality of the report depend on the quality of the DMI tables
 126 provided in each machine.  Here there are Intel machines without model
 127 information listed with Intel as vendor and mo model, and virtual Xen
 128 machines listed as [no-dmi-info].  One can add -l as a command line
 129 option to list the individual machines.</p>
 130
 131 <p>A larger list is
 132 <a href="http://narvikskolen.no/sitesummary/">available from the the
 133 city of Narvik</a>, which uses Skolelinux on all their shools and also
 134 provide the basic sitesummary report publicly.  In their report there
 135 are ~1400 machines. I know they use both Ubuntu and Skolelinux on
 136 their machines, and as sitesummary is available in both distributions,
 137 it is trivial to get all of them to report to the same central
 138 collector.</p>

 189 <p>If Debian is to migrate to upstart on Linux, I expect some init.d
 190 scripts to migrate (some of) their operations to upstart job while
 191 keeping the init.d for hurd and kfreebsd.  The packages with such
 192 needs will need a way to get their init.d scripts to behave
 193 differently when used with sysvinit and with upstart.  Because of
 194 this, I had a look at the environment variables set when a init.d
 195 script is running under upstart, and when it is not.</p>
 196
 197 <p>With upstart, I notice these environment variables are set when a
 198 script is started from rcS.d/ (ignoring some irrelevant ones like
 199 COLUMNS):</p>
 200
 201 <blockquote><pre>
 202 DEFAULT_RUNLEVEL=2
 203 previous=N
 204 PREVLEVEL=
 205 RUNLEVEL=
 206 runlevel=S
 207 UPSTART_EVENTS=startup
 208 UPSTART_INSTANCE=
 209 UPSTART_JOB=rc-sysinit
 210 </pre></blockquote>
 211
 212 <p>With sysvinit, these environment variables are set for the same
 213 script.</p>
 214
 215 <blockquote><pre>
 216 INIT_VERSION=sysvinit-2.88
 217 previous=N
 218 PREVLEVEL=N
 219 RUNLEVEL=S
 220 runlevel=S
 221 </pre></blockquote>
 222
 223 <p>The RUNLEVEL and PREVLEVEL environment variables passed on from
 224 sysvinit are not set by upstart.  Not sure if it is intentional or not
 225 to not be compatible with sysvinit in this regard.</p>
 226
 227 <p>For scripts needing to behave differently when upstart is used,
 228 looking for the UPSTART_JOB environment variable seem to be a good
 229 choice.</p>

 252 <p>Det er merkelig hvordan myter om Skolelinux overlever.  En slik
 253 myte er at Skolelinux ikke kan sentraldriftes og ha sentralt plasserte
 254 tjenermaskiner.  I siste Computerworld Norge er
 255 <a href="http://www.idg.no/computerworld/article169432.ece">IT-sjef
 256 Viggo Billdal i Steinkjer intervjuet</a>, og forteller uten
 257 blygsel:</p>
 258
 259 <blockquote><p>Vi hadde Skolelinux, men det har vi sluttet med. Vi testet
 260 om det lønte seg med Microsoft eller en åpen plattform. Vi fant ut at
 261 Microsoft egentlig var totalt sett bedre egnet. Det var store
 262 driftskostnader med Skolelinux, blant annet på grunn av
 263 desentraliserte servere. Det var komplisert, så vi gikk vekk fra det
 264 og bruker nå bare Windows.</p></blockquote>
 265
 266 <p>En <a
 267 href="https://init.linpro.no/pipermail/skolelinux.no/bruker/2010-June/009101.html">rask
 268 sjekk</a> mot den norske brukerlista i Skolelinuxprosjektet forteller
 269 at Steinkjers forsøk foregikk fram til 2004/2005, og at Røysing skole
 270 i Steinkjer skal ha vært svært fornøyd med Skolelinux men at kommunen
 271 overkjørte skolen og krevde at de gikk over til Windows.  Et søk på
 272 nettet sendte meg til
 273 <a href="http://www.dn.no/multimedia/archive/00090/Dagens_it_nr__18_90826a.pdf">Dagens
 274 IT nr. 18 2005</a> hvor en kan lese på side 18:</p>
 275
 276 <blockquote><p>Inge Tømmerås ved Røysing skole i Steinkjer kjører ennå
 277 Microsoft, men forteller at kompetanseutfordringen med Skolelinux ikke
 278 var så stor.   Jeg syntes Skolelinux var utrolig lett å drifte uten
 279 forkunnskaper. Men man må jo selvsagt ha tilgang på ekstern kompetanse
 280 til installasjoner og maskinvarefeil, sier Tømmerås.</p></blockquote>
 281
 282 <p>Som systemarkitekten bak Skolelinux, kan jeg bare riste på hodet
 283 over påstanden om at Skolelinux krever desentraliserte tjenere.
 284 Skolelinux-arkitekturen er laget for sentralisert drift og plassering
 285 av tjenerne lokalt eller sentralt alt etter behov og nettkapasitet.
 286 Den er modellert på nettverks- og tjenerløsningen som brukes på
 287 Universitetet i Tromsø og Oslo, der jeg jobber med utvikling av
 288 driftstjenester.  Dette er det heldigvis noen som har fått med seg, og
 289 jeg er glad for å kunne sitere fra en kommentar på den overnevnte
 290 artikkelen.  Min venn og gamle kollega Sturle Sunde forteller der:
 291
 292 <blockquote>
 293 <p>I Flora kommune køyrer vi Skulelinux på skular med alt frå 15 til
 294 meir enn 500 elevar. Dei store skulane har eigen tenar, for det er
 295 mest praktisk. Eg, som er driftsansvarleg for heile nettet, ser
 296 sjeldan dei tenarane fysisk, men at dei står der gjer skulane mindre
 297 avhengige av eksterne linjer som er trege eller dyre. Dei minste
 298 skulane har ikkje eigen tenar. Å bruke sentral tenar er heller ikkje
 299 noko problem. Småskulane klarar seg fint med 1 mbit-linje til ein
 300 sentral tenar eller tenaren på ein større skule.</p>
 301
 302 <p>Det beste med Skulelinux er halvtjukke klientar. Dei treng ikkje
 303 harddisk og brukar minimalt med ressursar på tenaren fordi dei køyrer
 304 programma lokalt. Eit klasserom med 30 sju-åtte år gamle maskiner har
 305 mykje meir CPU og RAM totalt enn nokon moderne tenar til under
 306 millionen. Det trengst to kommandoar på den sentrale tenaren for å
 307 oppdatere alle klientane, både tynne og halvtjukke. Vi har ingen
 308 problem med diskar som ryk heller, som var eit problem før fordi
 309 elevane sat og sparka i maskinene. Og dei krev lite bandbreidde i
 310 nettet, so det er fullt mogleg å køyre slike på småskular med trege
 311 linjer mot tenaren på ein større skule.</p>
 312
 313 <p>Flora kommune har nesten 800 Linux-maskiner i sitt skulenett, og
 314 ein person som tek seg av drift av heile nettet, inkludert tenarar,
 315 klientar, operativsystem, programvare, heimekontorløysing og
 316 administrasjon av brukarar.</p>
 317
 318 <p>No skal det seiast at vi ikkje køyrer rein Skulelinux ut av
 319 boksen. Vi har gjort ein del tilpassingar mot noko Novell-greier som
 320 var der frå før, og som har komplisert installasjonen vår. Etter at
 321 oppsettet var gjort har løysinga vore stabil og kravd minimalt med
 322 arbeid.</p>
 323 </blockquote>
 324
 325 <p>Jeg vet at Narvik, Harstad og Oslo er kommuner der Skolelinux
 326 sentraldriftes med sentrale tjenere.  Det forteller meg at Steinkjers
 327 IT-sjef neppe bør skylde på Skolelinux-løsningen for sine 5 år gamle
 328 minner.</p>

 350
 351 <p>The last few days I have done some upgrade testing in Debian, to
 352 see if the upgrade from Lenny to Squeeze will go smoothly.  A few bugs
 353 have been discovered and reported in the process
 354 (<a href="http://bugs.debian.org/585410">#585410</a> in nagios3-cgi,
 355 <a href="http://bugs.debian.org/584879">#584879</a> already fixed in
 356 enscript and <a href="http://bugs.debian.org/584861">#584861</a> in
 357 kdebase-workspace-data), and to get a more regular testing going on, I
 358 am working on a script to automate the test.</p>
 359
 360 <p>The idea is to create a Lenny chroot and use tasksel to install a
 361 Gnome or KDE desktop installation inside the chroot before upgrading
 362 it.  To ensure no services are started in the chroot, a policy-rc.d
 363 script is inserted.  To make sure tasksel believe it is to install a
 364 desktop on a laptop, the tasksel tests are replaced in the chroot
 365 (only acceptable because this is a throw-away chroot).</p>
 366
 367 <p>A naive upgrade from Lenny to Squeeze using aptitude dist-upgrade
 368 currently always fail because udev refuses to upgrade with the kernel
 369 in Lenny, so to avoid that problem the file /etc/udev/kernel-upgrade
 370 is created.  The bug report
 371 <a href="http://bugs.debian.org/566000">#566000</a> make me suspect
 372 this problem do not trigger in a chroot, but I touch the file anyway
 373 to make sure the upgrade go well.  Testing on virtual and real
 374 hardware have failed me because of udev so far, and creating this file
 375 do the trick in such settings anyway.  This is a
 376 <a href="http://www.linuxquestions.org/questions/debian-26/failed-dist-upgrade-due-to-udev-config_sysfs_deprecated-nonsense-804130/">known
 377 issue</a> and the current udev behaviour is intended by the udev
 378 maintainer because he lack the resources to rewrite udev to keep
 379 working with old kernels or something like that.  I really wish the
 380 udev upstream would keep udev backwards compatible, to avoid such
 381 upgrade problem, but given that they fail to do so, I guess
 382 documenting the way out of this mess is the best option we got for
 383 Debian Squeeze.</p>
 384
 385 <p>Anyway, back to the task at hand, testing upgrades.  This test
 386 script, which I call <tt>upgrade-test</tt> for now, is doing the
 387 trick:</p>

 448
 449 <p>I suspect it would be useful to test upgrades with both apt-get and
 450 with aptitude, but I have not had time to look at how they behave
 451 differently so far.  I hope to get a cron job running to do the test
 452 regularly and post the result on the web.  The Gnome upgrade currently
 453 work, while the KDE upgrade fail because of the bug in
 454 kdebase-workspace-data</p>
 455
 456 <p>I am not quite sure what kind of extract from the huge upgrade logs
 457 (KDE 167 KiB, Gnome 516 KiB) it make sense to include in this blog
 458 post, so I will refrain from trying.  I can report that for Gnome,

 464 <p>I am very happy to notice that the Gnome desktop + laptop upgrade
 465 is able to migrate to dependency based boot sequencing and parallel
 466 booting without a hitch.  Was unsure if there were still bugs with
 467 packages failing to clean up their obsolete init.d script during
 468 upgrades, and no such problem seem to affect the Gnome desktop+laptop
 469 packages.</p>

 492 <p>Veldig glad for å oppdage via
 493 <a href="http://yro.slashdot.org/story/10/06/11/1841256/Finland-To-Legalize-Use-of-Unsecured-Wi-Fi">Slashdot</a>
 494 at folk i Finland har forstått at åpne trådløsnett er et samfunnsgode.
 495 Jeg ser på åpne trådløsnett som et fellesgode på linje med retten til
 496 ferdsel i utmark og retten til å bevege seg i strandsonen.  Jeg har
 497 glede av åpne trådløsnett når jeg finner dem, og deler gladelig nett
 498 med andre så lenge de ikke forstyrrer min bruk av eget nett.
 499 Nettkapasiteten er sjelden en begrensning ved normal browsing og enkel
 500 SSH-innlogging (som er min vanligste nettbruk), og nett kan brukes til
 501 så mye positivt og nyttig (som nyhetslesing, sjekke været, kontakte
 502 slekt og venner, holde seg oppdatert om politiske saker, kontakte
 503 organisasjoner og politikere, etc), at det for meg er helt urimelig å
 504 blokkere dette for alle som ikke gjør en flue fortred.  De som mener
 505 at potensialet for misbruk er grunn nok til å hindre all den positive
 506 og lovlydige bruken av et åpent trådløsnett har jeg dermed ingen
 507 forståelse for.  En kan ikke eksistensen av forbrytere styre hvordan
 508 samfunnet skal organiseres.  Da får en et kontrollsamfunn de færreste
 509 ønsker å leve i, og det at vi har et samfunn i Norge der tilliten til
 510 hverandre er høy gjør at samfunnet fungerer ganske godt.  Det bør vi
 511 anstrenge oss for å beholde.</p>

 534 <p>My
 535 <a href="http://people.skolelinux.org/pere/blog/Automatic_upgrade_testing_from_Lenny_to_Squeeze.html">testing
 536 of Debian upgrades</a> from Lenny to Squeeze continues, and I've
 537 finally made the upgrade logs available from
 538 <a href="http://people.skolelinux.org/pere/debian-upgrade-testing/">http://people.skolelinux.org/pere/debian-upgrade-testing/</a>.
 539 I am now testing dist-upgrade of Gnome and KDE in a chroot using both
 540 apt and aptitude, and found their differences interesting.  This time
 541 I focus on their removal plans.</p>
 542
 543 <p>After installing a Gnome desktop and the laptop task, apt-get wants
 544 to remove 72 packages when dist-upgrading from Lenny to Squeeze.  The
 545 surprising part is that it want to remove xorg and all
 546 xserver-xorg-video* drivers.  Clearly not a good choice, but I am not
 547 sure why.  When asking aptitude to do the same, it want to remove 129
 548 packages, but most of them are library packages I suspect are no
 549 longer needed.  Both of them want to remove bluetooth packages, which
 550 I do not know.  Perhaps these bluetooth packages are obsolete?</p>
 551
 552 <p>For KDE, apt-get want to remove 82 packages, among them kdebase
 553 which seem like a bad idea and xorg the same way as with Gnome. Asking
 554 aptitude for the same, it wants to remove 192 packages, none which are
 555 too surprising.</p>
 556
 557 <p>I guess the removal of xorg during upgrades should be investigated
 558 and avoided, and perhaps others as well.  Here are the complete list
 559 of removals.  The complete logs is available from the URL above.  Note
 560 if you want to repeat these tests, that the upgrade test for
 561 kde+apt-get hung in the tasksel setup because of dpkg asking conffile
 562 questions.  No idea why.  I worked around it by using '<tt>echo >>
 563 /proc/<em>pidofdpkg</em>/fd/0</tt>' to tell dpkg to continue.</p>
