Hmm ...

there is nothing on debian that enforces that sethostname and
/etc/hostname stay in sync.

Also tools that dont rewrite /etc/hostname include NM itself and
things like "vi /etc/hostname" or echo newhostname > /etc/hostname.

So the next step is probably to add write support for /etc/hostname to
the ifupdown plugin.
