  24       <div class="date">18th August 2013</div>
  25       <div class="body"><p>Earlier, I reported about
  26 <a href="http://people.skolelinux.org/pere/blog/How_to_fix_a_Thinkpad_X230_with_a_broken_180_GB_SSD_disk.html">my
  27 problems using an Intel SSD 520 Series 180 GB disk</a>.  Friday I was
  28 told by IBM that the original disk should be thrown away.  And as
  29 there no longer was a problem if I bricked the firmware, I decided
  30 today to try to install Intel firmware to replace the Lenovo firmware
  31 currently on the disk.</p>
  32
  33 <p>I searched the Intel site for firmware, and found
  34 <a href="https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&ProdId=3472&DwnldID=18363&ProductFamily=Solid-State+Drives+and+Caching&ProductLine=Intel%c2%ae+High+Performance+Solid-State+Drive&ProductProduct=Intel%c2%ae+SSD+520+Series+(180GB%2c+2.5in+SATA+6Gb%2fs%2c+25nm%2c+MLC)&lang=eng">issdfut_2.0.4.iso</a>
  35 (aka Intel SATA Solid-State Drive Firmware Update Tool) which
  36 according to the site should contain the latest firmware for SSD
  37 disks.  I inserted the broken disk in one of my spare laptops and
  38 booted the ISO from a USB stick.  The disk was recognized, but the
  39 program claimed the newest firmware already were installed and refused
  40 to insert any Intel firmware.  So no change, and the disk is still
  41 unable to handle write load. :( I guess the only way to get them
  42 working would be if Lenovo releases new firmware.  No idea how likely
  43 that is.  Anyway, just blogging about this test for completeness.  I
  44 got a working Samsung disk, and see no point in spending more time on
  45 the broken disks.</p>

  59       <div class="date"> 2nd August 2013</div>
  60       <div class="body"><p>It has been a while since my last update.  Since last summer, I
  61 have worked on a Norwegian
  62 <a href="http://www.docbook.org/">docbook</a> version of the 2004 book
  63 <a href="http://free-culture.cc/">Free Culture</a> by Lawrence Lessig,
  64 to get a Norwegian text explaining the problems with the copyright
  65 law.  Yesterday, I finally broken the 90% mark, when counting the
  66 number of strings to translate.  Due to real life constraints, I have
  67 not had time to work on it since March, but when the summer broke out,
  68 I found time to work on it again.  Still lots of work left, but the
  69 first draft is nearing completion.  I created a graph to show the
  70 progress of the translation:</p>
  71
  72 <p><img width="80%" align="center" src="https://github.com/petterreinholdtsen/free-culture-lessig/raw/master/progress.png"></p>
  73
  74 <p>When the first draft is done, the translated text need to be
  75 proof read, and the remaining formatting problems with images and SVG
  76 drawings need to be fixed.  There are probably also some index entries
  77 missing that need to be added.  This can be done by comparing the
  78 index entries listed in the SiSU version of the book, or comparing the
  79 English docbook version with the paper version.  Last, the colophon
  80 page with ISBN numbers etc need to be wrapped up before the release is
  81 done.  I should also figure out how to get correct Norwegian sorting
  82 of the index pages.  All docbook tools I have tried so far (xmlto,
  83 docbook-xsl, dblatex) get the order of symbols and the special
  84 Norwegian letters ÆØÅ wrong.</p>
  85
  86 <p>There is still need for translators and people with docbook
  87 knowledge, to be able to get a good looking book (I still struggle
  88 with dblatex, xmlto and docbook-xsl) as well as to do the draft
  89 translation and proof reading.  And I would like the figures to be
  90 redrawn as SVGs to make it easy to translate them.  Any SVG master
  91 around?  There are also some legal terms that are unfamiliar to me.

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

 102 github hand it out with MIME type text/plain, confusing browsers, so I

 118       <div class="body"><p>The first wheezy based beta release of Debian Edu was wrapped up
 119 today.  This is the release announcement:</p>
 120
 121 <p><strong>New features for Debian Edu 7.1+edu0~b0 released
 122 2013-07-27</strong></p>
 123
 124 <p>These are the release notes for for Debian Edu / Skolelinux
 125 7.1+edu0~b0, based on Debian with codename "Wheezy".</p>
 126
 127 <p><strong>About Debian Edu and Skolelinux</strong></p>
 128
 129 <p><a href="http://www.skolelinux.org/">Debian Edu, also known as
 130 Skolelinux</a>, is a Linux distribution based on Debian providing an
 131 out-of-the box environment of a completely configured school
 132 network. Immediately after installation a school server running all
 133 services needed for a school network is set up just waiting for users
 134 and machines being added via GOsa², a comfortable Web-UI. A netbooting
 135 environment is prepared using PXE, so after initial installation of
 136 the main server from CD, DVD or USB stick all other machines can be
 137 installed via the network. The provided school server provides LDAP
 138 database and Kerberos authentication service, centralized home
 139 directories, DHCP server, web proxy and many other services. The
 140 desktop contains
 141 <a href="http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html">more
 142 than 60 educational software packages</a> and more are available from
 143 the Debian archive, and schools can choose between KDE, Gnome, LXDE
 144 and Xfce desktop environment.</p>
 145
 146 <p>This is the fifth test release based on Debian Wheezy. Basically
 147 this is an updated and slightly improved version compared to the
 148 Squeeze release.</p>
 149
 150 <p>ALERT: Alpha based installations should reinstall or downgrade the
 151 versions of gosa and libpam-mklocaluser to the ones used in this beta
 152 release.</p>
 153
 154 <p><strong>Software updates</strong></p>
 155
 156 <ul>
 157
 158 <li>Switched roaming workstation profiles from wicd to network-manager
 159    for network configuration, as wicd didn't work any more.</li>
 160 <li>Changed version numbers of patched gosa and libpam-mklocaluser
 161    packages to make sure our locally patched versions will be replaced
 162    by the official packages when they are released from Debian. Those
 163    installing alpha version need to reinstall or manually downgrade gosa
 164    and libpam-mklocaluser.</li>
 165 <li>Added bluetooth tools to the default desktop (bluedevil, blueman).</li>
 166 <li>Added tools for sharing the desktop on KDE (krdc, krfb).</li>
 167 <li>Added valgrind to the default installation for easier debugging of
 168    crash bugs.</li>
 169
 170 </ul>
 171
 172 <p><strong>Other changes</strong></p>
 173
 174 <ul>
 175
 176 <li>Fixed artwork package to work with gnome, no longer break
 177    desktop=gnome installations.</li>
 178 <li>Adjusted installer to now work when forced to use a proxy with the
 179    netinst CD.</li>
 180 <li>Fixed code detecting and setting/loading hardware specific
 181    setup/firmware to work more robust out of the box.</li>
 182 <li>Adjusted Kerberos setup to detect realm and server settings at
 183    install time instead of dynamically at run time. This avoid a crash
 184    with krb5-auth-dialog on diskless workstations without a DNS name.</li>
 185 <li>Worked around misfeature in network-manager not calling the dhclient
 186    exit hooks, causing automatic proxy configuration and automatic host
 187    name setting at run time to work again.</li>
 188 <li>Fixed feature setting the default Iceweasel start page from URL
 189    fetched from LDAP, to allow schools to set the global default by
 190    updating the dc=skole,dc=skolelinux,dc=no LDAP object.</li>
 191 <li>Changed default host name on all networked machines to be unique
 192    (generated from MAC or reverse DNS) after boot.</li>
 193 <li>Adjusted partition sizes to make sure they are big enough.</li>
 194
 195 </ul>

 255       <div class="date">17th July 2013</div>
 256       <div class="body"><p>Today I switched to
 257 <a href="http://people.skolelinux.org/pere/blog/The_Thinkpad_is_dead__long_live_the_Thinkpad_X230_.html">my
 258 new laptop</a>.  I've previously written about the problems I had with
 259 my new Thinkpad X230, which was delivered with an
 260 <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
 261 GB Intel SSD disk with Lenovo firmware</a> that did not handle
 262 sustained writes.  My hardware supplier have been very forthcoming in
 263 trying to find a solution, and after first trying with another
 264 identical 180 GB disks they decided to send me a 256 GB Samsung SSD
 265 disk instead to fix it once and for all.  The Samsung disk survived
 266 the installation of Debian with encrypted disks (filling the disk with
 267 random data during installation killed the first two), and I thus
 268 decided to trust it with my data.  I have installed it as a Debian Edu
 269 Wheezy roaming workstation hooked up with my Debian Edu Squeeze main
 270 server at home using Kerberos and LDAP, and will use it as my work
 271 station from now on.</p>
 272
 273 <p>As this is a solid state disk with no moving parts, I believe the
 274 Debian Wheezy default installation need to be tuned a bit to increase
 275 performance and increase life time of the disk.  The Linux kernel and
 276 user space applications do not yet adjust automatically to such
 277 environment.  To make it easier for my self, I created a draft Debian
 278 package <tt>ssd-setup</tt> to handle this tuning.  The
 279 <a href="http://anonscm.debian.org/gitweb/?p=collab-maint/ssd-setup.git">source
 280 for the ssd-setup package</a> is available from collab-maint, and it
 281 is set up to adjust the setup of the machine by just installing the
 282 package.  If there is any non-SSD disk in the machine, the package
 283 will refuse to install, as I did not try to write any logic to sort
 284 file systems in SSD and non-SSD file systems.</p>
 285
 286 <p>I consider the package a draft, as I am a bit unsure how to best
 287 set up Debian Wheezy with an SSD.  It is adjusted to my use case,
 288 where I set up the machine with one large encrypted partition (in
 289 addition to /boot), put LVM on top of this and set up partitions on
 290 top of this again.  See the README file in the package source for the
 291 references I used to pick the settings.  At the moment these
 292 parameters are tuned:</p>
 293
 294 <ul>
 295
 296 <li>Set up cryptsetup to pass TRIM commands to the physical disk
 297     (adding discard to /etc/crypttab)</li>
 298
 299 <li>Set up LVM to pass on TRIM commands to the underlying device (in
 300     this case a cryptsetup partition) by changing issue_discards from
 301     0 to 1 in /etc/lvm/lvm.conf.</li>
 302
 303 <li>Set relatime as a file system option for ext3 and ext4 file
 304     systems.</li>
 305
 306 <li>Tell swap to use TRIM commands by adding 'discard' to
 307     /etc/fstab.</li>
 308
 309 <li>Change I/O scheduler from cfq to deadline using a udev rule.</li>
 310
 311 <li>Run fstrim on every ext3 and ext4 file system every night (from
 312     cron.daily).</li>
 313
 314 <li>Adjust sysctl values vm.swappiness to 1 and vm.vfs_cache_pressure
 315     to 50 to reduce the kernel eagerness to swap out processes.</li>
 316
 317 </ul>
 318
 319 <p>During installation, I cancelled the part where the installer fill
 320 the disk with random data, as this would kill the SSD performance for
 321 little gain.  My goal with the encrypted file system is to ensure
 322 those stealing my laptop end up with a brick and not a working
 323 computer.  I have no hope in keeping the really resourceful people
 324 from getting the data on the disk (see
 325 <a href="http://xkcd.com/538/">XKCD #538</a> for an explanation why).
 326 Thus I concluded that adding the discard option to crypttab is the
 327 right thing to do.</p>
 328
 329 <p>I considered using the noop I/O scheduler, as several recommended
 330 it for SSD, but others recommended deadline and a benchmark I found
 331 indicated that deadline might be better for interactive use.</p>
 332
 333 <p>I also considered using the 'discard' file system option for ext3
 334 and ext4, but read that it would give a performance hit ever time a
 335 file is removed, and thought it best to that that slowdown once a day
 336 instead of during my work.</p>
 337
 338 <p>My package do not set up tmpfs on /var/run, /var/lock and /tmp, as
 339 this is already done by Debian Edu.</p>
 340
 341 <p>I have not yet started on the user space tuning.  I expect
 342 iceweasel need some tuning, and perhaps other applications too, but
 343 have not yet had time to investigate those parts.</p>
 344
 345 <p>The package should work on Ubuntu too, but I have not yet tested it
 346 there.</p>
 347
 348 <p>As for the answer to the question in the title of this blog post,
 349 as far as I know, the only solution I know about is to replace the
 350 disk.  It might be possible to flash it with Intel firmware instead of
 351 the Lenovo firmware.  But I have not tried and did not want to do so
 352 without approval from Lenovo as I wanted to keep the warranty on the
 353 disk until a solution was found and they wanted the broken disks
 354 back.</p>

 368       <div class="date">10th July 2013</div>
 369       <div class="body"><p>A few days ago, I wrote about
 370 <a href="http://people.skolelinux.org/pere/blog/The_Thinkpad_is_dead__long_live_the_Thinkpad_X230_.html">the
 371 problems I experienced with my new X230 and its SSD disk</a>, which
 372 was dying during installation because it is unable to cope with
 373 sustained write.  My supplier is in contact with
 374 <a href="http://www.lenovo.com/">Lenovo</a>, and they wanted to send a
 375 replacement disk to try to fix the problem.  They decided to send an
 376 identical model, so my hopes for a permanent fix was slim.</p>
 377
 378 <p>Anyway, today I got the replacement disk and tried to install
 379 Debian Edu Wheezy with encrypted disk on it.  The new disk have the
 380 same firmware version as the original.  This time my hope raised
 381 slightly as the installation progressed, as the original disk used to
 382 die after 4-7% of the disk was written to, while this time it kept
 383 going past 10%, 20%, 40% and even past 50%.  But around 60%, the disk
 384 died again and I was back on square one.  I still do not have a new
 385 laptop with a disk I can trust.  I can not live with a disk that might
 386 lock up when I download a new
 387 <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a> ISO or
 388 other large files.  I look forward to hearing from my supplier with
 389 the next proposal from Lenovo.</p>

 450       <div class="date"> 5th July 2013</div>
 451       <div class="body"><p>Half a year ago, I reported that I had to find a
 452 <a href="http://people.skolelinux.org/pere/blog/Thank_you_Thinkpad_X41__for_your_long_and_trustworthy_service.html">replacement
 453 for my trusty old Thinkpad X41</a>.  Unfortunately I did not have much
 454 time to spend on it, and it took a while to find a model I believe
 455 will do the job, but two days ago the replacement finally arrived.  I
 456 ended up picking a
 457 <a href="http://www.linlap.com/lenovo_thinkpad_x230">Thinkpad X230</a>
 458 with SSD disk (NZDAJMN).  I first test installed Debian Edu Wheezy as
 459 a roaming workstation, and it seemed to work flawlessly.  But my
 460 second installation with encrypted disk was not as successful.  More
 461 on that below.</p>
 462
 463 <p>I had a hard time trying to track down a good laptop, as my most
 464 important requirements (robust and with a good keyboard) are never
 465 listed in the feature list.  But I did get good help from the search
 466 feature at <a href="http://www.prisjakt.no/">Prisjakt</a>, which
 467 allowed me to limit the list of interesting laptops based on my other
 468 requirements.  A bit surprising that SSD disk are not disks according
 469 to that search interface, so I had to drop specifying the number of
 470 disks from my search parameters.  I also asked around among friends to
 471 get their impression on keyboards and robustness.</p>
 472
 473 <p>So the new laptop arrived, and it is quite a lot wider than the
 474 X41.  I am not quite convinced about the keyboard, as it is
 475 significantly wider than my old keyboard, and I have to stretch my
 476 hand a lot more to reach the edges.  But the key response is fairly
 477 good and the individual key shape is fairly easy to handle, so I hope
 478 I will get used to it.  My old X40 was starting to fail, and I really
 479 needed a new laptop now. :)</p>
 480
 481 <p>Turning off the touch pad was simple.  All it took was a quick
 482 visit to the BIOS during boot it disable it.</p>
 483
 484 <p>But there is a fatal problem with the laptop.  The 180 GB SSD disk
 485 lock up during load.  And this happen when installing Debian Wheezy
 486 with encrypted disk, while the disk is being filled with random data.
 487 I also tested to install Ubuntu Raring, and it happen there too if I
 488 reenable the code to fill the disk with random data (it is disabled by
 489 default in Ubuntu).  And the bug with is already known.  It was
 490 reported to Debian as <a href="http://bugs.debian.org/691427">BTS
 491 report #691427 2012-10-25</a> (journal commit I/O error on brand-new
 492 Thinkpad T430s ext4 on lvm on SSD).  It is also reported to the Linux
 493 kernel developers as
 494 <a href="https://bugzilla.kernel.org/show_bug.cgi?id=51861">Kernel bugzilla
 495 report #51861 2012-12-20</a> (Intel SSD 520 stops working under load
 496 (SSDSC2BW180A3L in Lenovo ThinkPad T430s)). It is also reported on the
 497 Lenovo forums, both for
 498 <a href="http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T430s-Intel-SSD-520-180GB-issue/m-p/1070549">T430
 499 2012-11-10</a> and for
 500 <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
 501 03-20-2013</a>.  The problem do not only affect installation.  The
 502 reports state that the disk lock up during use if many writes are done
 503 on the disk, so it is much no use to work around the installation
 504 problem and end up with a computer that can lock up at any moment.
 505 There is even a
 506 <a href="https://git.efficios.com/?p=test-ssd.git">small C program
 507 available</a> that will lock up the hard drive after running a few
 508 minutes by writing to a file.</p>
 509
 510 <p>I've contacted my supplier and asked how to handle this, and after
 511 contacting PCHELP Norway (request 01D1FDP) which handle support
 512 requests for Lenovo, his first suggestion was to upgrade the disk
 513 firmware.  Unfortunately there is no newer firmware available from
 514 Lenovo, as my disk already have the most recent one (version LF1i).  I
 515 hope to hear more from him today and hope the problem can be
 516 fixed. :)</p>

 574 <p><strong>New features for Debian Edu 7.1+edu0~alpha3 released
 575 2013-07-03</strong></p>

 577 <p>These are the release notes for for Debian Edu / Skolelinux

 579
 580 <p><strong>About Debian Edu and Skolelinux</strong></p>
 581
 582 <p><a href="http://www.skolelinux.org/">Debian Edu, also known as
 583 Skolelinux</a>, is a Linux distribution based on Debian providing an
 584 out-of-the box environment of a completely configured school
 585 network. Immediately after installation a school server running all
 586 services needed for a school network is set up just waiting for users
 587 and machines being added via GOsa², a comfortable Web-UI. A netbooting
 588 environment is prepared using PXE, so after initial installation of
 589 the main server from CD, DVD or USB stick all other machines can be
 590 installed via the network. The provided school server provides LDAP
 591 database and Kerberos authentication service, centralized home
 592 directories, DHCP server, web proxy and many other services. The
 593 desktop contains
 594 <a href="http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html">more
 595 than 60 educational software packages</a> and more are available from
 596 the Debian archive, and schools can choose between KDE, Gnome, LXDE
 597 and Xfce desktop environment.</p>
 598
 599 <p>This is the fourth test release based on Debian Wheezy. Basically
 600 this is an updated and slightly improved version compared to the
 601 Squeeze release.</p>
 602
 603 <p><strong>Software updates</strong></p>
 604 <ul>
 605   <li>Dropped ispell dictionaries from our default installation.</li>
 606   <li>Dropped menu-xdg from the KDE desktop option, to drop the Debian
 607     submenu.  It was not included with Gnome, LXDE or Xfce, so this
 608     brings KDE in line with the others.</li>
 609   <li>Dropped xdrawchem, xjig and xsok from our default installation as
 610     they don't have a desktop menu entry and thus won't show up in the
 611     menu now that menu-xdg was removed.</li>
 612   <li>Removed the killer system to kill left behind processes on
 613     multi-user machines, as it was no longer able to understand when a
 614     X display was in use and killed the processes of the active users
 615     too.</li>
 616   <li>Dropped the golearn (from goplay) package as the debtags in wheezy
 617     are too few to make the package useful.</li>
 618 </ul>
 619 <p><strong>Other changes</strong></p>
 620 <ul>
 621   <li>Updated artwork matching http://wiki.debian.org/DebianArt/Themes/Joy
 622   <li>Multi-arch i386/amd64 USB stick ISO available.</li>
 623   <li>Got rid of ispell/wordlist related debconf questions that showed
 624     up for some language options.</li>
 625   <li>Switched to using http.debian.net as APT source by default.</li>
 626   <li>Fixed proxy configuration on Main Server installations.</li>
 627   <li>Changed LTSP setup to ask dpkg to use force-unsafe-io the same way
 628     d-i is doing it.</li>
 629   <li>Made sure root and user passwords were not left behind in the
 630     debconf database after installation on Main Server installations.</li>
 631   <li>Made Roaming Workstation dynamic setup more robust and added draft
 632     script setup-ad-client to hook a Roaming Workstation up to a
 633     Active Directory server instead of a Debian Edu Main Server.</li>
 634   <li>Update system to install needed firmware packages during
 635     installation, to work properly in Wheezy.</li>
 636   <li>Update system to handle hardware quirks (debian-edu-hwsetup).</li>
 637   <li>Corrected PXE installation setup to properly pass selected desktop
 638     and keymap settings to PXE installation clients.</li>
 639   <li>LTSP diskless workstations use sshfs by default, allowing them to
 640     work without adding them to DNS and NIS netgroups for NFS access.</li>
 641 </ul>
 642 <p><strong>Known issues</strong></p>
 643 <ul>
 644   <li>No mass import of user account data in GOsa (ldif or csv)
 645     available yet (698840).</li>
 646   <li>Artwork not enabled for all desktops.</li>

 686       <div class="date">25th June 2013</div>
 687       <div class="body"><p>It annoys me when the computer fail to do automatically what it is
 688 perfectly capable of, and I have to do it manually to get things
 689 working.  One such task is to find out what firmware packages are
 690 needed to get the hardware on my computer working.  Most often this
 691 affect the wifi card, but some times it even affect the RAID
 692 controller or the ethernet card.  Today I pushed version 0.4 of the
 693 <a href="http://packages.qa.debian.org/isenkram">Isenkram package</a>
 694 including a new script isenkram-autoinstall-firmware handling the
 695 process of asking all the loaded kernel modules what firmware files
 696 they want, find debian packages providing these files and install the
 697 debian packages.  Here is a test run on my laptop:</p>
 698
 699 <p><pre>
 700 # isenkram-autoinstall-firmware
 701 info: kernel drivers requested extra firmware: ipw2200-bss.fw ipw2200-ibss.fw ipw2200-sniffer.fw
 702 info: fetching http://http.debian.net/debian/dists/squeeze/Contents-i386.gz
 703 info: locating packages with the requested firmware files
 704 info: Updating APT sources after adding non-free APT source
 705 info: trying to install firmware-ipw2x00
 706 firmware-ipw2x00
 707 firmware-ipw2x00
 708 Preconfiguring packages ...
 709 Selecting previously deselected package firmware-ipw2x00.
 710 (Reading database ... 259727 files and directories currently installed.)
 711 Unpacking firmware-ipw2x00 (from .../firmware-ipw2x00_0.28+squeeze1_all.deb) ...
 712 Setting up firmware-ipw2x00 (0.28+squeeze1) ...
 713 #
 714 </pre></p>
 715
 716 <p>When all the requested firmware is present, a simple message is
 717 printed instead:</p>
 718
 719 <p><pre>
 720 # isenkram-autoinstall-firmware
 721 info: did not find any firmware files requested by loaded kernel modules.  exiting
 722 #
 723 </pre></p>
 724
 725 <p>It could use some polish, but it is already working well and saving
 726 me some time when setting up new machines. :)</p>
 727
 728 <p>So, how does it work?  It look at the set of currently loaded
 729 kernel modules, and look up each one of them using modinfo, to find
 730 the firmware files listed in the module meta-information.  Next, it
 731 download the Contents file from a nearby APT mirror, and search for
 732 the firmware files in this file to locate the package with the
 733 requested firmware file.  If the package is in the non-free section, a
 734 non-free APT source is added and the package is installed using
 735 <tt>apt-get install</tt>.  The end result is a slightly better working
 736 machine.</p>
 737
 738 <p>I hope someone find time to implement a more polished version of
 739 this script as part of the hw-detect debian-installer module, to
 740 finally fix <a href="http://bugs.debian.org/655507">BTS report
 741 #655507</a>.  There really is no need to insert USB sticks with
 742 firmware during a PXE install when the packages already are available
 743 from the nearby Debian mirror.</p>
