[Pkg-sysvinit-devel] Bug#628140: initscripts: /etc/init.d/hostname.sh fails if /etc/hostname not present

[Edgar Fuss]

Package: initscripts
Version: 2.88dsf-13.1
Severity: normal
Tags: patch

If /etc/hostname is not present, /etc/init.d/hostname.sh will pick up the kernel supplied hostname ``(none)'' and try to set this via hostname(1), wich fails.
The obvious fix is to treat a hostname of ``(none)'' as, ehm, none, e.g. empty.
This will give you a hostname of ``localhost''.
