  26 <p>If Debian is to migrate to upstart on Linux, I expect some init.d
  27 scripts to migrate (some of) their operations to upstart job while
  28 keeping the init.d for hurd and kfreebsd.  The packages with such
  29 needs will need a way to get their init.d scripts to behave
  30 differently when used with sysvinit and with upstart.  Because of
  31 this, I had a look at the environment variables set when a init.d
  32 script is running under upstart, and when it is not.</p>
  33
  34 <p>With upstart, I notice these environment variables are set when a
  35 script is started from rcS.d/ (ignoring some irrelevant ones like
  36 COLUMNS):</p>
  37
  38 <blockquote><pre>
  39 DEFAULT_RUNLEVEL=2
  40 previous=N
  41 PREVLEVEL=
  42 RUNLEVEL=
  43 runlevel=S
  44 UPSTART_EVENTS=startup
  45 UPSTART_INSTANCE=
  46 UPSTART_JOB=rc-sysinit
  47 </pre></blockquote>
  48
  49 <p>With sysvinit, these environment variables are set for the same
  50 script.</p>
  51
  52 <blockquote><pre>
  53 INIT_VERSION=sysvinit-2.88
  54 previous=N
  55 PREVLEVEL=N
  56 RUNLEVEL=S
  57 runlevel=S
  58 </pre></blockquote>
  59
  60 <p>The RUNLEVEL and PREVLEVEL environment variables passed on from
  61 sysvinit is not set by upstart.  Not sure if it is intentional or not
  62 to not be compatible with sysvinit in this regard.</p>
  63
  64 <p>For scripts needing to behave differently when upstart is used,
  65 looking for the UPSTART_JOB environment variable seem to be a good
  66 choice.</p>

 103 <p>When using sitesummary at a site to track machines, it is possible
 104 to get a list of the machine types in use thanks to the DMI
 105 information extracted from each machine.  The script to do so is
 106 included in the sitesummary package, and here is example output from
 107 the Skolelinux build servers:</p>
 108
 109 <blockquote><pre>

 111   vendor                    count

 120
 121 <p>The quality of the report depend on the quality of the DMI tables
 122 provided in each machine.  Here there are Intel machines without model
 123 information listed with Intel as vendor and mo model, and virtual Xen
 124 machines listed as [no-dmi-info].  One can add -l as a command line
 125 option to list the individual machines.</p>
 126
 127 <p>A larger list is
 128 <a href="http://narvikskolen.no/sitesummary/">available from the the
 129 city of Narvik</a>, which uses Skolelinux on all their shools and also
 130 provide the basic sitesummary report publicly.  In their report there
 131 are ~1400 machines. I know they use both Ubuntu and Skolelinux on
 132 their machines, and as sitesummary is available in both distributions,
 133 it is trivial to get all of them to report to the same central
 134 collector.</p>

 171   <div class="body">
 172 <p>It is strange to watch how a bug in Debian causing KDM to fail to
 173 start at boot when an NVidia video card is used is handled.  The
 174 problem seem to be that the nvidia X.org driver uses a long time to
 175 initialize, and this duration is longer than kdm is configured to
 176 wait.</p>
 177
 178 <p>I came across two bugs related to this issue,
 179 <a href="http://bugs.debian.org/583312">#583312</a> initially filed
 180 against initscripts and passed on to nvidia-glx when it became obvious
 181 that the nvidia drivers were involved, and
 182 <a href="http://bugs.debian.org/524751">#524751</a> initially filed against
 183 kdm and passed on to src:nvidia-graphics-drivers for unknown reasons.</p>
 184
 185 <p>To me, it seem that no-one is interested in actually solving the
 186 problem nvidia video card owners experience and make sure the Debian
 187 distribution work out of the box for these users.  The nvidia driver
 188 maintainers expect kdm to be set up to wait longer, while kdm expect
 189 the nvidia driver maintainers to fix the driver to start faster, and
 190 while they wait for each other I guess the users end up switching to a
 191 distribution that work for them.  I have no idea what the solution is,
 192 but I am pretty sure that waiting for each other is not it.</p>
 193
 194 <p>I wonder why we end up handling bugs this way.</p>

 210 <p>A few days ago, parallel booting was enabled in Debian/testing.
 211 The feature seem to hold up pretty well, but three fairly serious
 212 issues are known and should be solved:
 213
 214 <p><ul>
 215
 216 <li>The wicd package seen to
 217 <a href="http://bugs.debian.org/508289">break NFS mounting</a> and
 218 <a href="http://bugs.debian.org/581586">network setup</a> when
 219 parallel booting is enabled.  No idea why, but the wicd maintainer
 220 seem to be on the case.</li>
 221
 222 <li>The nvidia X driver seem to
 223 <a href="http://bugs.debian.org/583312">have a race condition</a>
 224 triggered more easily when parallel booting is in effect.  The
 225 maintainer is on the case.</li>
 226
 227 <li>The sysv-rc package fail to properly enable dependency based boot
 228 sequencing (the shutdown is broken) when old file-rc users
 229 <a href="http://bugs.debian.org/575080">try to switch back</a> to
 230 sysv-rc.  One way to solve it would be for file-rc to create
 231 /etc/init.d/.legacy-bootordering, and another is to try to make
 232 sysv-rc more robust.  Will investigate some more and probably upload a
 233 workaround in sysv-rc to help those trying to move from file-rc to
 234 sysv-rc get a working shutdown.</li>
 235
 236 </ul></p>
 237
 238 <p>All in all not many surprising issues, and all of them seem
 239 solvable before Squeeze is released.  In addition to these there are
 240 some packages with bugs in their dependencies and run level settings,
 241 which I expect will be fixed in a reasonable time span.</p>
 242
 243 <p>If you report any problems with dependencies in init.d scripts to
 244 the BTS, please usertag the report to get it to show up at
 245 <a href="http://bugs.debian.org/cgi-bin/pkgreport.cgi?users=initscripts-ng-devel@lists.alioth.debian.org">the
 246 list of usertagged bugs related to this</a>.</p>

 262   <div class="date">2010-05-22 21:30</div>
 263   <div class="body">
 264 <p>After a long break from debian-installer development, I finally
 265 found time today to return to the project.  Having to spend less time
 266 working dependency based boot in debian, as it is almost complete now,
 267 definitely helped freeing some time.</p>
 268
 269 <p>A while back, I ran into a problem while working on Debian Edu.  We
 270 include some firmware packages on the Debian Edu CDs, those needed to
 271 get disk and network controllers working.  Without having these
 272 firmware packages available during installation, it is impossible to
 273 install Debian Edu on the given machine, and because our target group
 274 are non-technical people, asking them to provide firmware packages on
 275 an external medium is a support pain.  Initially, I expected it to be
 276 enough to include the firmware packages on the CD to get
 277 debian-installer to find and use them.  This proved to be wrong.
 278 Next, I hoped it was enough to symlink the relevant firmware packages
 279 to some useful location on the CD (tried /cdrom/ and
 280 /cdrom/firmware/).  This also proved to not work, and at this point I
 281 found time to look at the debian-installer code to figure out what was
 282 going to work.</p>
 283
 284 <p>The firmware loading code is in the hw-detect package, and a closer
 285 look revealed that it would only look for firmware packages outside
 286 the installation media, so the CD was never checked for firmware
 287 packages.  It would only check USB sticks, floppies and other
 288 "external" media devices.  Today I changed it to also look in the
 289 /cdrom/firmware/ directory on the mounted CD or DVD, which should
 290 solve the problem I ran into with Debian edu.  I also changed it to
 291 look in /firmware/, to make sure the installer also find firmware
 292 provided in the initrd when booting the installer via PXE, to allow us
 293 to provide the same feature in the PXE setup included in Debian
 294 Edu.</p>
 295
 296 <p>To make sure firmware deb packages with a license questions are not
 297 activated without asking if the license is accepted, I extended
 298 hw-detect to look for preinst scripts in the firmware packages, and
 299 run these before activating the firmware during installation.  The
 300 license question is asked using debconf in the preinst, so this should
 301 solve the issue for the firmware packages I have looked at so far.</p>
 302
 303 <p>If you want to discuss the details of these features, please
 304 contact us on debian-boot@lists.debian.org.</p>

 323 skulle dele innholdet på to kort med mine lesere.</p>
 324
 325 <p>For noen dager siden tok jeg flyet til Harstad og Hurtigruten til

 347 Aner ikke hva innholdet representerer, og det er lite overlapp mellom
 348 det jeg ser trykket på billetten og det jeg ser av tegn i

 387   <div class="date">2010-05-19 19:00</div>
 388   <div class="body">
 389 <p>Today, the last piece of the puzzle for roaming laptops in Debian
 390 Edu finally entered the Debian archive.  Today, the new
 391 <a href="http://packages.qa.debian.org/libp/libpam-mklocaluser.html">libpam-mklocaluser</a>
 392 package was accepted.  Two days ago, two other pieces was accepted
 393 into unstable.  The
 394 <a href="http://packages.qa.debian.org/p/pam-python.html">pam-python</a>
 395 package needed by libpam-mklocaluser, and the
 396 <a href="http://packages.qa.debian.org/s/sssd.html">sssd</a> package
 397 passed NEW on Monday.  In addition, the
 398 <a href="http://packages.qa.debian.org/libp/libpam-ccreds.html">libpam-ccreds</a>
 399 package we need is in experimental (version 10-4) since Saturday, and
 400 hopefully will be moved to unstable soon.</p>
 401
 402 <p>This collection of packages allow for two different setups for
 403 roaming laptops.  The traditional setup would be using libpam-ccreds,
 404 nscd and libpam-mklocaluser with LDAP or Kerberos authentication,
 405 which should work out of the box if the configuration changes proposed
 406 for nscd in <a href="http://bugs.debian.org/485282">BTS report
 407 #485282</a> is implemented.  The alternative setup is to use sssd with
 408 libpam-mklocaluser to connect to LDAP or Kerberos and let sssd take
 409 care of the caching of passwords and group information.</p>
 410
 411 <p>I have so far been unable to get sssd to work with the LDAP server
 412 at the University, but suspect the issue is some SSL/GnuTLS related
 413 problem with the server certificate.  I plan to update the Debian
 414 package to version 1.2, which is scheduled for next week, and hope to
 415 find time to make sure the next release will include both the
 416 Debian/Ubuntu specific patches.  Upstream is friendly and responsive,
 417 and I am sure we will find a good solution.</p>
 418
 419 <p>The idea is to set up the roaming laptops to authenticate using
 420 LDAP or Kerberos and create a local user with home directory in /home/
 421 when a usre in LDAP logs in via KDM or GDM for the first time, and
 422 cache the password for offline checking, as well as caching group
 423 memberhips and other relevant LDAP information.  The
 424 libpam-mklocaluser package was created to make sure the local home
 425 directory is in /home/, instead of /site/server/directory/ which would
 426 be the home directory if pam_mkhomedir was used.  To avoid confusion
 427 with support requests and configuration, we do not want local laptops
 428 to have users in a path that is used for the same users home directory
 429 on the home directory servers.</p>
 430
 431 <p>One annoying problem with gdm is that it do not show the PAM
 432 message passed to the user from libpam-mklocaluser when the local user
 433 is created.  Instead gdm simply reject the login with some generic
 434 message.  The message is shown in kdm, ssh and login, so I guess it is
 435 a bug in gdm.  Have not investigated if there is some other message
 436 type that can be used instead to get gdm to also show the message.</p>

 455 <p>Since this evening, parallel booting is the default in
 456 Debian/unstable for machines using dependency based boot sequencing.
 457 Apparently the testing of concurrent booting has been wider than
 458 expected, if I am to believe the
 459 <a href="http://lists.debian.org/debian-devel/2010/05/msg00122.html">input
 460 on debian-devel@</a>, and I concluded a few days ago to move forward
 461 with the feature this weekend, to give us some time to detect any
 462 remaining problems before Squeeze is frozen.  If serious problems are
 463 detected, it is simple to change the default back to sequential boot.
 464 The upload of the new sysvinit package also activate a new upstream
 465 version.</p>
 466
 467 More information about
 468 <a href="http://wiki.debian.org/LSBInitScripts/DependencyBasedBoot">dependency
 469 based boot sequencing</a> is available from the Debian wiki.  It is
 470 currently possible to disable parallel booting when one run into
 471 problems caused by it, by adding this line to /etc/default/rcS:</p>
 472
 473 <blockquote><pre>
 474 CONCURRENCY=none
 475 </pre></blockquote>
 476
 477 <p>If you report any problems with dependencies in init.d scripts to
 478 the BTS, please usertag the report to get it to show up at
