Bug#928756: debian-edu-config: search domain not configured correctly on diskless workstations in subnet00



Package: debian-edu-config
Version: 2.10.64
Severity: important

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256

The following misbehaviour occurs reproducibly in a new installation of
Debian Edu buster.

 1. Install a combined server like normal.
 2. Add a machine on the LTSP network 192.168.0.0/32 as in the screenshot.
 3. Boot that machine as diskless workstation.

If done like that, the /etc/resolv.conf generated at boot by ltsp-init with
the information provided by 08-edu-hostname is missing a search domain entry
(it should probably be subnet00.intern intern).  Thus, short hostnames, like
used by the default Firefox start page, are not resolvable.

The configuration of the search domain works perfectly on the main network
10.0.0.0/16.

I only tested on (two different) combined servers, not on a dedicated
terminal server.
