- <description><p>It annoys me when the computer fail to do automatically what it is
-perfectly capable of, and I have to do it manually to get things
-working. One such task is to find out what firmware packages are
-needed to get the hardware on my computer working. Most often this
-affect the wifi card, but some times it even affect the RAID
-controller or the ethernet card. Today I pushed version 0.4 of the
-<a href="http://packages.qa.debian.org/isenkram">Isenkram package</a>
-including a new script isenkram-autoinstall-firmware handling the
-process of asking all the loaded kernel modules what firmware files
-they want, find debian packages providing these files and install the
-debian packages. Here is a test run on my laptop:</p>
-
-<p><pre>
-# isenkram-autoinstall-firmware
-info: kernel drivers requested extra firmware: ipw2200-bss.fw ipw2200-ibss.fw ipw2200-sniffer.fw
-info: fetching http://http.debian.net/debian/dists/squeeze/Contents-i386.gz
-info: locating packages with the requested firmware files
-info: Updating APT sources after adding non-free APT source
-info: trying to install firmware-ipw2x00
-firmware-ipw2x00
-firmware-ipw2x00
-Preconfiguring packages ...
-Selecting previously deselected package firmware-ipw2x00.
-(Reading database ... 259727 files and directories currently installed.)
-Unpacking firmware-ipw2x00 (from .../firmware-ipw2x00_0.28+squeeze1_all.deb) ...
-Setting up firmware-ipw2x00 (0.28+squeeze1) ...
-#
-</pre></p>
-
-<p>When all the requested firmware is present, a simple message is
-printed instead:</p>
-
-<p><pre>
-# isenkram-autoinstall-firmware
-info: did not find any firmware files requested by loaded kernel modules. exiting
-#
-</pre></p>
-
-<p>It could use some polish, but it is already working well and saving
-me some time when setting up new machines. :)</p>
-
-<p>So, how does it work? It look at the set of currently loaded
-kernel modules, and look up each one of them using modinfo, to find
-the firmware files listed in the module meta-information. Next, it
-download the Contents file from a nearby APT mirror, and search for
-the firmware files in this file to locate the package with the
-requested firmware file. If the package is in the non-free section, a
-non-free APT source is added and the package is installed using
-<tt>apt-get install</tt>. The end result is a slightly better working
-machine.</p>
-
-<p>I hope someone find time to implement a more polished version of
-this script as part of the hw-detect debian-installer module, to
-finally fix <a href="http://bugs.debian.org/655507">BTS report
-#655507</a>. There really is no need to insert USB sticks with
-firmware during a PXE install when the packages already are available
-from the nearby Debian mirror.</p>

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

-please join us on

- <description><p>The <a href="http://www.skolelinux.org/">Debian Edu and
-Skolelinux</a> distribution have users and contributors all around the
-globe. And a while back, an enterprising young man showed up on
-<a href="irc://irc.debian.org/%23debian-edu">our IRC channel
-#debian-edu</a> and started asking questions about how Debian Edu
-worked. We answered as good as we could, and even convinced him to
-help us with translations. And today I managed to get an interview
-with him, to learn more about him.</p>
