In debian, as far as I can see, all daemons should be enabled by
default. if you want to disable them, just remove the links in /etc/rc?.d.

nfs is the only one that is disabled by default, as far as I know.

nfs doesn't come with an exports file like
  /    *(rw,no_root_squash)
but rather with an empty one. That doesn't pose a security threat.
And, had Alex had an /etc/exports file like the one above, Alex
probably had a good reason for it (i.e. he only has a local network).

In my opinion, nfs should just install like the rest of the daemons.

An hour?
 # rm /etc/rc2.d/*

Does that take an hour? (OK it deletes more than you want to,
but selecting the right ones still doesn't get close to an hour).
