  24       <div class="date"> 2nd August 2013</div>
  25       <div class="body"><p>It has been a while since my last update.  Since last summer, I
  26 have worked on a Norwegian
  27 <a href="http://www.docbook.org/">docbook</a> version of the 2004 book
  28 <a href="http://free-culture.cc/">Free Culture</a> by Lawrence Lessig,
  29 to get a Norwegian text explaining the problems with the copyright
  30 law.  Yesterday, I finally broken the 90% mark, when counting the
  31 number of strings to translate.  Due to real life constraints, I have
  32 not had time to work on it since March, but when the summer broke out,
  33 I found time to work on it again.  Still lots of work left, but the
  34 first draft is nearing completion.  I created a graph to show the
  35 progress of the translation:</p>
  36
  37 <p><img width="80%" align="center" src="https://github.com/petterreinholdtsen/free-culture-lessig/raw/master/progress.png"></p>
  38
  39 <p>When the first draft is done, the translated text need to be
  40 proof read, and the remaining formatting problems with images and SVG
  41 drawings need to be fixed.  There are probably also some index entries
  42 missing that need to be added.  This can be done by comparing the
  43 index entries listed in the SiSU version of the book, or comparing the
  44 English docbook version with the paper version.  Last, the colophon
  45 page with ISBN numbers etc need to be wrapped up before the release is
  46 done.  I should also figure out how to get correct Norwegian sorting
  47 of the index pages.  All docbook tools I have tried so far (xmlto,
  48 docbook-xsl, dblatex) get the order of symbols and the special
  49 Norwegian letters ÆØÅ wrong.</p>
  50
  51 <p>There is still need for translators and people with docbook
  52 knowledge, to be able to get a good looking book (I still struggle
  53 with dblatex, xmlto and docbook-xsl) as well as to do the draft
  54 translation and proof reading.  And I would like the figures to be
  55 redrawn as SVGs to make it easy to translate them.  Any SVG master
  56 around?  There are also some legal terms that are unfamiliar to me.

  58 project files currently available from
  59 <a href="https://github.com/petterreinholdtsen/free-culture-lessig">github</a>.</p>

  66 are published on github.  The HTML version is published as well, but
  67 github hand it out with MIME type text/plain, confusing browsers, so I
  68 saw no point in linking to that version.</p>

  82       <div class="date">27th July 2013</div>
  83       <div class="body"><p>The first wheezy based beta release of Debian Edu was wrapped up
  84 today.  This is the release announcement:</p>
  85
  86 <p><strong>New features for Debian Edu 7.1+edu0~b0 released
  87 2013-07-27</strong></p>
  88
  89 <p>These are the release notes for for Debian Edu / Skolelinux
  90 7.1+edu0~b0, based on Debian with codename "Wheezy".</p>
  91
  92 <p><strong>About Debian Edu and Skolelinux</strong></p>
  93
  94 <p><a href="http://www.skolelinux.org/">Debian Edu, also known as
  95 Skolelinux</a>, is a Linux distribution based on Debian providing an
  96 out-of-the box environment of a completely configured school
  97 network. Immediately after installation a school server running all
  98 services needed for a school network is set up just waiting for users
  99 and machines being added via GOsa², a comfortable Web-UI. A netbooting
 100 environment is prepared using PXE, so after initial installation of
 101 the main server from CD, DVD or USB stick all other machines can be
 102 installed via the network. The provided school server provides LDAP
 103 database and Kerberos authentication service, centralized home
 104 directories, DHCP server, web proxy and many other services. The
 105 desktop contains
 106 <a href="http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html">more
 107 than 60 educational software packages</a> and more are available from
 108 the Debian archive, and schools can choose between KDE, Gnome, LXDE
 109 and Xfce desktop environment.</p>
 110
 111 <p>This is the fifth test release based on Debian Wheezy. Basically
 112 this is an updated and slightly improved version compared to the
 113 Squeeze release.</p>
 114
 115 <p>ALERT: Alpha based installations should reinstall or downgrade the
 116 versions of gosa and libpam-mklocaluser to the ones used in this beta
 117 release.</p>
 118
 119 <p><strong>Software updates</strong></p>
 120
 121 <ul>
 122
 123 <li>Switched roaming workstation profiles from wicd to network-manager
 124    for network configuration, as wicd didn't work any more.</li>
 125 <li>Changed version numbers of patched gosa and libpam-mklocaluser
 126    packages to make sure our locally patched versions will be replaced
 127    by the official packages when they are released from Debian. Those
 128    installing alpha version need to reinstall or manually downgrade gosa
 129    and libpam-mklocaluser.</li>
 130 <li>Added bluetooth tools to the default desktop (bluedevil, blueman).</li>
 131 <li>Added tools for sharing the desktop on KDE (krdc, krfb).</li>
 132 <li>Added valgrind to the default installation for easier debugging of
 133    crash bugs.</li>
 134
 135 </ul>
 136
 137 <p><strong>Other changes</strong></p>
 138
 139 <ul>
 140
 141 <li>Fixed artwork package to work with gnome, no longer break
 142    desktop=gnome installations.</li>
 143 <li>Adjusted installer to now work when forced to use a proxy with the
 144    netinst CD.</li>
 145 <li>Fixed code detecting and setting/loading hardware specific
 146    setup/firmware to work more robust out of the box.</li>
 147 <li>Adjusted Kerberos setup to detect realm and server settings at
 148    install time instead of dynamically at run time. This avoid a crash
 149    with krb5-auth-dialog on diskless workstations without a DNS name.</li>
 150 <li>Worked around misfeature in network-manager not calling the dhclient
 151    exit hooks, causing automatic proxy configuration and automatic host
 152    name setting at run time to work again.</li>
 153 <li>Fixed feature setting the default Iceweasel start page from URL
 154    fetched from LDAP, to allow schools to set the global default by
 155    updating the dc=skole,dc=skolelinux,dc=no LDAP object.</li>
 156 <li>Changed default host name on all networked machines to be unique
 157    (generated from MAC or reverse DNS) after boot.</li>
 158 <li>Adjusted partition sizes to make sure they are big enough.</li>
 159
 160 </ul>
 161
 162 <p><strong>Known issues</strong></p>
 163
 164 <ul>
 165
 166 <li>Grub is missing the new artwork.</li>
 167 <li>KDE fail to understand the wpad.dat file provided, causing it to

 220       <div class="date">17th July 2013</div>
 221       <div class="body"><p>Today I switched to
 222 <a href="http://people.skolelinux.org/pere/blog/The_Thinkpad_is_dead__long_live_the_Thinkpad_X230_.html">my
 223 new laptop</a>.  I've previously written about the problems I had with
 224 my new Thinkpad X230, which was delivered with an
 225 <a href="http://people.skolelinux.org/pere/blog/Intel_SSD_520_Series_180_GB_with_Lenovo_firmware_still_lock_up_from_sustained_writes.html">180
 226 GB Intel SSD disk with Lenovo firmware</a> that did not handle
 227 sustained writes.  My hardware supplier have been very forthcoming in
 228 trying to find a solution, and after first trying with another
 229 identical 180 GB disks they decided to send me a 256 GB Samsung SSD
 230 disk instead to fix it once and for all.  The Samsung disk survived
 231 the installation of Debian with encrypted disks (filling the disk with
 232 random data during installation killed the first two), and I thus
 233 decided to trust it with my data.  I have installed it as a Debian Edu
 234 Wheezy roaming workstation hooked up with my Debian Edu Squeeze main
 235 server at home using Kerberos and LDAP, and will use it as my work
 236 station from now on.</p>
 237
 238 <p>As this is a solid state disk with no moving parts, I believe the
 239 Debian Wheezy default installation need to be tuned a bit to increase
 240 performance and increase life time of the disk.  The Linux kernel and
 241 user space applications do not yet adjust automatically to such
 242 environment.  To make it easier for my self, I created a draft Debian
 243 package <tt>ssd-setup</tt> to handle this tuning.  The
 244 <a href="http://anonscm.debian.org/gitweb/?p=collab-maint/ssd-setup.git">source
 245 for the ssd-setup package</a> is available from collab-maint, and it
 246 is set up to adjust the setup of the machine by just installing the
 247 package.  If there is any non-SSD disk in the machine, the package
 248 will refuse to install, as I did not try to write any logic to sort
 249 file systems in SSD and non-SSD file systems.</p>
 250
 251 <p>I consider the package a draft, as I am a bit unsure how to best
 252 set up Debian Wheezy with an SSD.  It is adjusted to my use case,
 253 where I set up the machine with one large encrypted partition (in
 254 addition to /boot), put LVM on top of this and set up partitions on
 255 top of this again.  See the README file in the package source for the
 256 references I used to pick the settings.  At the moment these
 257 parameters are tuned:</p>
 258
 259 <ul>
 260
 261 <li>Set up cryptsetup to pass TRIM commands to the physical disk
 262     (adding discard to /etc/crypttab)</li>
 263
 264 <li>Set up LVM to pass on TRIM commands to the underlying device (in
 265     this case a cryptsetup partition) by changing issue_discards from
 266     0 to 1 in /etc/lvm/lvm.conf.</li>
 267
 268 <li>Set relatime as a file system option for ext3 and ext4 file
 269     systems.</li>
 270
 271 <li>Tell swap to use TRIM commands by adding 'discard' to
 272     /etc/fstab.</li>
 273
 274 <li>Change I/O scheduler from cfq to deadline using a udev rule.</li>
 275
 276 <li>Run fstrim on every ext3 and ext4 file system every night (from
 277     cron.daily).</li>
 278
 279 <li>Adjust sysctl values vm.swappiness to 1 and vm.vfs_cache_pressure
 280     to 50 to reduce the kernel eagerness to swap out processes.</li>
 281
 282 </ul>
 283
 284 <p>During installation, I cancelled the part where the installer fill
 285 the disk with random data, as this would kill the SSD performance for
 286 little gain.  My goal with the encrypted file system is to ensure
 287 those stealing my laptop end up with a brick and not a working
 288 computer.  I have no hope in keeping the really resourceful people
 289 from getting the data on the disk (see
 290 <a href="http://xkcd.com/538/">XKCD #538</a> for an explanation why).
 291 Thus I concluded that adding the discard option to crypttab is the
 292 right thing to do.</p>
 293
 294 <p>I considered using the noop I/O scheduler, as several recommended
 295 it for SSD, but others recommended deadline and a benchmark I found
 296 indicated that deadline might be better for interactive use.</p>
 297
 298 <p>I also considered using the 'discard' file system option for ext3
 299 and ext4, but read that it would give a performance hit ever time a
 300 file is removed, and thought it best to that that slowdown once a day
 301 instead of during my work.</p>
 302
 303 <p>My package do not set up tmpfs on /var/run, /var/lock and /tmp, as
 304 this is already done by Debian Edu.</p>
 305
 306 <p>I have not yet started on the user space tuning.  I expect
 307 iceweasel need some tuning, and perhaps other applications too, but
 308 have not yet had time to investigate those parts.</p>
 309
 310 <p>The package should work on Ubuntu too, but I have not yet tested it
 311 there.</p>
 312
 313 <p>As for the answer to the question in the title of this blog post,
 314 as far as I know, the only solution I know about is to replace the
 315 disk.  It might be possible to flash it with Intel firmware instead of
 316 the Lenovo firmware.  But I have not tried and did not want to do so
 317 without approval from Lenovo as I wanted to keep the warranty on the
 318 disk until a solution was found and they wanted the broken disks
 319 back.</p>

 333       <div class="date">10th July 2013</div>
 334       <div class="body"><p>A few days ago, I wrote about
 335 <a href="http://people.skolelinux.org/pere/blog/The_Thinkpad_is_dead__long_live_the_Thinkpad_X230_.html">the
 336 problems I experienced with my new X230 and its SSD disk</a>, which
 337 was dying during installation because it is unable to cope with
 338 sustained write.  My supplier is in contact with
 339 <a href="http://www.lenovo.com/">Lenovo</a>, and they wanted to send a
 340 replacement disk to try to fix the problem.  They decided to send an
 341 identical model, so my hopes for a permanent fix was slim.</p>
 342
 343 <p>Anyway, today I got the replacement disk and tried to install
 344 Debian Edu Wheezy with encrypted disk on it.  The new disk have the
 345 same firmware version as the original.  This time my hope raised
 346 slightly as the installation progressed, as the original disk used to
 347 die after 4-7% of the disk was written to, while this time it kept
 348 going past 10%, 20%, 40% and even past 50%.  But around 60%, the disk
 349 died again and I was back on square one.  I still do not have a new
 350 laptop with a disk I can trust.  I can not live with a disk that might
 351 lock up when I download a new
 352 <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a> ISO or
 353 other large files.  I look forward to hearing from my supplier with
 354 the next proposal from Lenovo.</p>

 415       <div class="date"> 5th July 2013</div>
 416       <div class="body"><p>Half a year ago, I reported that I had to find a
 417 <a href="http://people.skolelinux.org/pere/blog/Thank_you_Thinkpad_X41__for_your_long_and_trustworthy_service.html">replacement
 418 for my trusty old Thinkpad X41</a>.  Unfortunately I did not have much
 419 time to spend on it, and it took a while to find a model I believe
 420 will do the job, but two days ago the replacement finally arrived.  I
 421 ended up picking a
 422 <a href="http://www.linlap.com/lenovo_thinkpad_x230">Thinkpad X230</a>
 423 with SSD disk (NZDAJMN).  I first test installed Debian Edu Wheezy as
 424 a roaming workstation, and it seemed to work flawlessly.  But my
 425 second installation with encrypted disk was not as successful.  More
 426 on that below.</p>
 427
 428 <p>I had a hard time trying to track down a good laptop, as my most
 429 important requirements (robust and with a good keyboard) are never
 430 listed in the feature list.  But I did get good help from the search
 431 feature at <a href="http://www.prisjakt.no/">Prisjakt</a>, which
 432 allowed me to limit the list of interesting laptops based on my other
 433 requirements.  A bit surprising that SSD disk are not disks according
 434 to that search interface, so I had to drop specifying the number of
 435 disks from my search parameters.  I also asked around among friends to
 436 get their impression on keyboards and robustness.</p>
 437
 438 <p>So the new laptop arrived, and it is quite a lot wider than the
 439 X41.  I am not quite convinced about the keyboard, as it is
 440 significantly wider than my old keyboard, and I have to stretch my
 441 hand a lot more to reach the edges.  But the key response is fairly
 442 good and the individual key shape is fairly easy to handle, so I hope
 443 I will get used to it.  My old X40 was starting to fail, and I really
 444 needed a new laptop now. :)</p>
 445
 446 <p>Turning off the touch pad was simple.  All it took was a quick
 447 visit to the BIOS during boot it disable it.</p>
 448
 449 <p>But there is a fatal problem with the laptop.  The 180 GB SSD disk
 450 lock up during load.  And this happen when installing Debian Wheezy
 451 with encrypted disk, while the disk is being filled with random data.
 452 I also tested to install Ubuntu Raring, and it happen there too if I
 453 reenable the code to fill the disk with random data (it is disabled by
 454 default in Ubuntu).  And the bug with is already known.  It was
 455 reported to Debian as <a href="http://bugs.debian.org/691427">BTS
 456 report #691427 2012-10-25</a> (journal commit I/O error on brand-new
 457 Thinkpad T430s ext4 on lvm on SSD).  It is also reported to the Linux
 458 kernel developers as
 459 <a href="https://bugzilla.kernel.org/show_bug.cgi?id=51861">Kernel bugzilla
 460 report #51861 2012-12-20</a> (Intel SSD 520 stops working under load
 461 (SSDSC2BW180A3L in Lenovo ThinkPad T430s)). It is also reported on the
 462 Lenovo forums, both for
 463 <a href="http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T430s-Intel-SSD-520-180GB-issue/m-p/1070549">T430
 464 2012-11-10</a> and for
 465 <a href="http://forums.lenovo.com/t5/X-Series-ThinkPad-Laptops/x230-SATA-errors-with-180GB-Intel-520-SSD-under-heavy-write-load/m-p/1068147">X230
 466 03-20-2013</a>.  The problem do not only affect installation.  The
 467 reports state that the disk lock up during use if many writes are done
 468 on the disk, so it is much no use to work around the installation
 469 problem and end up with a computer that can lock up at any moment.
 470 There is even a
 471 <a href="https://git.efficios.com/?p=test-ssd.git">small C program
 472 available</a> that will lock up the hard drive after running a few
 473 minutes by writing to a file.</p>
 474
 475 <p>I've contacted my supplier and asked how to handle this, and after
 476 contacting PCHELP Norway (request 01D1FDP) which handle support
 477 requests for Lenovo, his first suggestion was to upgrade the disk
 478 firmware.  Unfortunately there is no newer firmware available from
 479 Lenovo, as my disk already have the most recent one (version LF1i).  I
 480 hope to hear more from him today and hope the problem can be
 481 fixed. :)</p>

 536       <div class="body"><p>The fourth wheezy based alpha release of Debian Edu was wrapped up
 537 today.  This is the release announcement:</p>
 538
 539 <p><strong>New features for Debian Edu 7.1+edu0~alpha3 released
 540 2013-07-03</strong></p>
 541
 542 <p>These are the release notes for for Debian Edu / Skolelinux
 543 7.1+edu0~alpha3, based on Debian with codename "Wheezy".</p>
 544
 545 <p><strong>About Debian Edu and Skolelinux</strong></p>
 546
 547 <p><a href="http://www.skolelinux.org/">Debian Edu, also known as
 548 Skolelinux</a>, is a Linux distribution based on Debian providing an
 549 out-of-the box environment of a completely configured school
 550 network. Immediately after installation a school server running all
 551 services needed for a school network is set up just waiting for users
 552 and machines being added via GOsa², a comfortable Web-UI. A netbooting
 553 environment is prepared using PXE, so after initial installation of
 554 the main server from CD, DVD or USB stick all other machines can be
 555 installed via the network. The provided school server provides LDAP
 556 database and Kerberos authentication service, centralized home
 557 directories, DHCP server, web proxy and many other services. The
 558 desktop contains
 559 <a href="http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html">more
 560 than 60 educational software packages</a> and more are available from
 561 the Debian archive, and schools can choose between KDE, Gnome, LXDE
 562 and Xfce desktop environment.</p>
 563
 564 <p>This is the fourth test release based on Debian Wheezy. Basically
 565 this is an updated and slightly improved version compared to the
 566 Squeeze release.</p>
 567
 568 <p><strong>Software updates</strong></p>
 569 <ul>
 570   <li>Dropped ispell dictionaries from our default installation.</li>
 571   <li>Dropped menu-xdg from the KDE desktop option, to drop the Debian
 572     submenu.  It was not included with Gnome, LXDE or Xfce, so this
 573     brings KDE in line with the others.</li>
 574   <li>Dropped xdrawchem, xjig and xsok from our default installation as
 575     they don't have a desktop menu entry and thus won't show up in the
 576     menu now that menu-xdg was removed.</li>
 577   <li>Removed the killer system to kill left behind processes on
 578     multi-user machines, as it was no longer able to understand when a
 579     X display was in use and killed the processes of the active users
 580     too.</li>
 581   <li>Dropped the golearn (from goplay) package as the debtags in wheezy
 582     are too few to make the package useful.</li>
 583 </ul>
 584 <p><strong>Other changes</strong></p>
 585 <ul>
 586   <li>Updated artwork matching http://wiki.debian.org/DebianArt/Themes/Joy
 587   <li>Multi-arch i386/amd64 USB stick ISO available.</li>
 588   <li>Got rid of ispell/wordlist related debconf questions that showed
 589     up for some language options.</li>
 590   <li>Switched to using http.debian.net as APT source by default.</li>
 591   <li>Fixed proxy configuration on Main Server installations.</li>
 592   <li>Changed LTSP setup to ask dpkg to use force-unsafe-io the same way
 593     d-i is doing it.</li>
 594   <li>Made sure root and user passwords were not left behind in the
 595     debconf database after installation on Main Server installations.</li>
 596   <li>Made Roaming Workstation dynamic setup more robust and added draft
 597     script setup-ad-client to hook a Roaming Workstation up to a
 598     Active Directory server instead of a Debian Edu Main Server.</li>
 599   <li>Update system to install needed firmware packages during
 600     installation, to work properly in Wheezy.</li>
 601   <li>Update system to handle hardware quirks (debian-edu-hwsetup).</li>
 602   <li>Corrected PXE installation setup to properly pass selected desktop
 603     and keymap settings to PXE installation clients.</li>
 604   <li>LTSP diskless workstations use sshfs by default, allowing them to
 605     work without adding them to DNS and NIS netgroups for NFS access.</li>
 606 </ul>
 607 <p><strong>Known issues</strong></p>
 608 <ul>
 609   <li>No mass import of user account data in GOsa (ldif or csv)
 610     available yet (698840).</li>
 611   <li>Artwork not enabled for all desktops.</li>

 651       <div class="date">25th June 2013</div>
 652       <div class="body"><p>It annoys me when the computer fail to do automatically what it is
 653 perfectly capable of, and I have to do it manually to get things
 654 working.  One such task is to find out what firmware packages are
 655 needed to get the hardware on my computer working.  Most often this
 656 affect the wifi card, but some times it even affect the RAID
 657 controller or the ethernet card.  Today I pushed version 0.4 of the
 658 <a href="http://packages.qa.debian.org/isenkram">Isenkram package</a>
 659 including a new script isenkram-autoinstall-firmware handling the
 660 process of asking all the loaded kernel modules what firmware files
 661 they want, find debian packages providing these files and install the
 662 debian packages.  Here is a test run on my laptop:</p>
 663
 664 <p><pre>
 665 # isenkram-autoinstall-firmware
 666 info: kernel drivers requested extra firmware: ipw2200-bss.fw ipw2200-ibss.fw ipw2200-sniffer.fw
 667 info: fetching http://http.debian.net/debian/dists/squeeze/Contents-i386.gz
 668 info: locating packages with the requested firmware files
 669 info: Updating APT sources after adding non-free APT source
 670 info: trying to install firmware-ipw2x00
 671 firmware-ipw2x00
 672 firmware-ipw2x00
 673 Preconfiguring packages ...
 674 Selecting previously deselected package firmware-ipw2x00.
 675 (Reading database ... 259727 files and directories currently installed.)
 676 Unpacking firmware-ipw2x00 (from .../firmware-ipw2x00_0.28+squeeze1_all.deb) ...
 677 Setting up firmware-ipw2x00 (0.28+squeeze1) ...
 678 #
 679 </pre></p>
 680
 681 <p>When all the requested firmware is present, a simple message is
 682 printed instead:</p>
 683
 684 <p><pre>
 685 # isenkram-autoinstall-firmware
 686 info: did not find any firmware files requested by loaded kernel modules.  exiting
 687 #
 688 </pre></p>
 689
 690 <p>It could use some polish, but it is already working well and saving
 691 me some time when setting up new machines. :)</p>
 692
 693 <p>So, how does it work?  It look at the set of currently loaded
 694 kernel modules, and look up each one of them using modinfo, to find
 695 the firmware files listed in the module meta-information.  Next, it
 696 download the Contents file from a nearby APT mirror, and search for
 697 the firmware files in this file to locate the package with the
 698 requested firmware file.  If the package is in the non-free section, a
 699 non-free APT source is added and the package is installed using
 700 <tt>apt-get install</tt>.  The end result is a slightly better working
 701 machine.</p>
 702
 703 <p>I hope someone find time to implement a more polished version of
 704 this script as part of the hw-detect debian-installer module, to
 705 finally fix <a href="http://bugs.debian.org/655507">BTS report
 706 #655507</a>.  There really is no need to insert USB sticks with
 707 firmware during a PXE install when the packages already are available
 708 from the nearby Debian mirror.</p>

 722       <div class="date">22nd June 2013</div>
 723       <div class="body"><p>In the <a href="http://www.skolelinux.org/">Debian Edu /
 724 Skolelinux</a> project, we include a post-installation test suite,
 725 which check that services are running, working, and return the
 726 expected results.  It runs automatically just after the first boot on
 727 test installations (using test ISOs), but not on production
 728 installations (using non-test ISOs).  It test that the LDAP service is
 729 operating, Kerberos is responding, DNS is replying, file systems are
 730 online resizable, etc, etc.  And it check that the PXE service is
 731 configured, which is the topic of this post.</p>
 732
 733 <p>The last week I've fixed the DVD and USB stick ISOs for our Debian
 734 Edu Wheezy release.  These ISOs are supposed to be able to install a
 735 complete system without any Internet connection, but for that to
 736 happen all the needed packages need to be on them.  Thanks to our test
 737 suite, I discovered that we had forgotten to adjust our PXE setup to
 738 cope with the new names and paths used by the netboot d-i packages.
 739 When Internet connectivity was available, the installer fall back to
 740 using wget to fetch d-i boot images, but when offline it require
 741 working packages to get it working.  And the packages changed name
 742 from debian-installer-6.0-netboot-$arch to
 743 debian-installer-7.0-netboot-$arch, we no longer pulled in the
 744 packages during installation.  Without our test suite, I suspect we
 745 would never have discovered this before release.  Now it is fixed
 746 right after we got the ISOs operational.</p>
 747
 748 <p>Another by-product of the test suite is that we can ask system
 749 administrators with problems getting Debian Edu to work, to run the
 750 test suite using <tt>/usr/sbin/debian-edu-test-install</tt> and see if
 751 any errors are detected.  This usually pinpoint the subsystem causing
