has permission to mess with the nodes specified. Some general cleanup.
Redo the freebsd approach completely. Instead of copying over the current
rc.conf.local and munging it, I build them up locally and just overwrite
what is on the node. This cuts down on the number of ssh/scp commands that
get invoked (which appear to cause all kinds of problems). Its also more
rebust than trying to devine whats in that file. In fact, we should change
/etc/rc.conf to load, say, /etc/rc.conf.tbifc so avoid any clashes with
local stuff that might/will exist in that file.
