I think that depends on how you define "mistake".
Reading hostname(1):
FILES
/etc/hostname Historically this file was supposed to only
contain the hostname and not the full canonical FQDN. Nowadays
most software is able to cope with a full FQDN here. This file is
read at boot time by the system initialization scripts to set the
hostname.
/etc/hosts Usually, this is where one sets the domain name by
aliasing the host name to the FQDN.
I know this is not what most Unix admins expect because Debian diverts
from the standard here, or used to. However, as the manual says, "most
software is able to cope with a full FQDN here". My point of view is
that we should rather stay in line with the Debian installer, and "most
software" is not "all software". I have recently at least seen one
backup tool fail because of this (although I agree it shouldn't break).
So, my opinion is: If there is no good reason in Debian Edu (as in,
software breaking, not beliefs), we should strip the domain part there
like Debian itself normally does.
