No, we don't need xdm in runlevel 4. A better solution would be this (but
it is more difficult, requires multiple inetd.conf files):-

2: multiuser, minimal networking, no networking daemons (including inetd).
3: multiuser, "client" networking (rpc.ugidd, ident, etc.)
4: multiuser, "server" networking (ftp, http, finger, etc.)

Yes, good idea.

It doesn't need to be disabled, it just saves memory. It will detect when
X starts up, and give up its own handling of the mouse. Only PS/2 mouse
devices used cause a major problem with this (single-open only), but they 
don't do that any more IIRC.

I think a better way than doing runlevels directly in packages, though,
may be to set a package startup script's "type" - minnet, netclient,
netserver, misc, etc. Then, define runlevels to include certain "types"
of script. Just an idea (very difficult to implement with symlinks for
/etc/rc?.d), what does anyone else think?
