Testbed Master Control Daemon. Catchy name, eh? Note that tmcd runs

on paper. tmcc runs on the testbed nodes. The linux and freebsd directories
have the scripts and skeleton passwd/group file stuff. There are makefiles
in those directories for installing on the testbed node (typically before
you cut an image!).
