  25       <div class="body"><p>In the <a href="http://www.skolelinux.org/">Debian Edu /
  26 Skolelinux</a> project, we include a post-installation test suite,
  27 which check that services are running, working, and return the
  28 expected results.  It runs automatically just after the first boot on
  29 test installations (using test ISOs), but not on production
  30 installations (using non-test ISOs).  It test that the LDAP service is
  31 operating, Kerberos is responding, DNS is replying, file systems are
  32 online resizable, etc, etc.  And it check that the PXE service is
  33 configured, which is the topic of this post.</p>
  34
  35 <p>The last week I've fixed the DVD and USB stick ISOs for our Debian
  36 Edu Wheezy release.  These ISOs are supposed to be able to install a
  37 complete system without any Internet connection, but for that to
  38 happen all the needed packages need to be on them.  Thanks to our test
  39 suite, I discovered that we had forgotten to adjust our PXE setup to
  40 cope with the new names and paths used by the netboot d-i packages.
  41 When Internet connectivity was available, the installer fall back to
  42 using wget to fetch d-i boot images, but when offline it require
  43 working packages to get it working.  And the packages changed name
  44 from debian-installer-6.0-netboot-$arch to
  45 debian-installer-7.0-netboot-$arch, we no longer pulled in the
  46 packages during installation.  Without our test suite, I suspect we
  47 would never have discovered this before release.  Now it is fixed
  48 right after we got the ISOs operational.</p>
  49
  50 <p>Another by-product of the test suite is that we can ask system
  51 administrators with problems getting Debian Edu to work, to run the
  52 test suite using <tt>/usr/sbin/debian-edu-test-install</tt> and see if
  53 any errors are detected.  This usually pinpoint the subsystem causing
  54 the problem.</p>
