("service xinetd reload" or "/etc/init.d/xinetd reload" on redhat)

At least on redhat boxes, if chkconfig is used to manage xinetd
services (recommended when available - I suspect that mandrake has
it too), then these changes are initiated right away (since it
automatically tells xinetd to reload).  (However, it doesn't auto
start/stop /etc/init.d/ services).

chkconfig can be a very useful little tool, eg:

# display the services activated at runlevel 3:
$ chkconfig --list | grep 3:on

# display the services NOT activated at runlevel 3:
$ chkconfig --list | grep 3:off

# show the state of all the xinetd services:
$ chkconfig --list | grep -v 3:o

# exactly mirror the rc bootup state of runlevel 3 to runlevel 4:
$ for s in $(chkconfig --list | grep 3:off | cut -d\  -f1) ; do \
  chkconfig --level 4 $s off ; done
$ for s in $(chkconfig --list | grep 3:on | cut -d\  -f1) ; do \
  chkconfig --level 4 $s on ; done

... etc.

It is a pity that xinetd (or inetd) can't be configured to run
different sets of services on a per-level basis (the daemon is
either running with the same set of services, or not running).

(Interesting... someone recently mentioned runlevels 7-9, chkconfig
doesn't handle that at all:)
