Consider the folowing:

ssh server -l root
# dpkg --purge ssh
Connection closed by foreign host

Purging ssh would kill shhd, which would kill the dpkg, which would
leafe the system in a very inconsistent state.

Same with xdm, killing it might get you beaten up by the users.


Daemons like ssh or xdm should be stoped from accepting any new
connections but not killed. For xdm this would mean quit all xdm
display where noone is currently locked in.

Just my 2c worth of thought.

May the Source be with you.
