priority of netcfg/get_domain

[Josef Wolf]

Hello,

In netconf-1.40ubuntu1, the debconf priority for netcfg/get_domain is
reduced to medium.  As a consequence, the installer no longer asks for
the domain name.  This is fine as long as a domain name is provided
e.g. via dhcp.  But without dhcp, the domain name will be left empty.
Unfortunately, many packages need a proper domain configuration.
There is even no way to force d-i to ask for a domain name with
preseeding.

Anybody knows why the priority was lowered from high to medium?  Is
there a way to force d-i to ask for a domain name when none is provided
via dhcp?
