set hostname from xen domain name in DOMUs?

[Matthias Drochner <M.Drochner%fz-juelich.de@localhost>]

I've found it practical to have the hostname set to
the domain name before "dhclient" is called. It makes
it simpler to clone a domu, in particular if dynamic
IP addresses are used.
So I created this little rc.d script.
Does this make sense? Should I add it to
pkgsrc/xenstoretools?

best regards
Matthias
