The "link" is the file /dev/MAKEDEV" -- that is, the relationship
is not guaranteed to be 1:1, and required user intervention to
establish.

This means that the /dev nodes can be "stale" relative to the
actual devices.

This will be fixed automatically when devfs becomes mandatory (if this
ever happens).

The X server runs on one console per reference -- the first free
vty, as a matter of fact.

You will have to run multiple X servers to have multiple consoles with
xdm presenting a login box.

See the xdm documentation and the XFree86 release notes for FreeBSD
for details.
