How about a Linux Administration / Linux in the Enterprise administration forum. Something that would be a place for discussion about managing a linux device or multiple linux devices in a network.. Things like cfengine, linuxconf, webmin .. different tips and tricks, different utilities, functions/daemons in linux and how you can manage or adminster them. Installation over the network, replication/ghost/imaging and deployment, patchingetc etc.

Things like that.

Or maybe that's already covered in a forum somewhere?

Just a suggestion.
