shutting off DTR

[Bill Kennedy]

Not to detract from what the others said about stopping up DTR
in single user mode, but you should also be careful about what
processes you let run via /etc/inittab.  The second field spells
out what run levels you want the line to affect.

I've seen some systems who just arbitrarily use 1234 for things
like spawning uugetty's and other things that you clearly don't
want at run level 1 (single user).  The man page suggests that
changing from multi-user to single user might kill any processes
that shouldn't be run, but I've not seen it or tried it.
