chkconfig is a chimaera of update-rc.d++ and a sysvinit-editor:
* Listing: chkconfig --list
* Incremental changing: chkconfig --level 4 portmap off
with update-rc.d you'd have to explicitly specify that you _still_
want portmap on in runlevel 3 _and_ use the -f Option.
chkconfig'll remove the links while the init-script is still there.
chkconfig --add is roughly aequivalent to "update-rc.d add defaults"
with the addition that it reads the default runlevels from the
init-script itself.
chkconfig can be used to control services started by xinetd, too.
chkconfig includes all the functionality of update-rc.d and
behaves very differently than update-rc.d, it does not really fit into
Debians init-system. chkconfig's usability is severly reduced until
_we_ ship runlevel-defaults in our initscripts, too.
Imho it'd be nice to have:
-list-rc.d, which'll output the current configuration.
-default-runlevels coded in the initscript[1]. (At this time you'll
have to look in /var/lib/dpkg/info/*.postinst if you want to find
out what the original runlevel-config was.)
If the former were implemented (and required by policy) it'd be easy
to write a nice switch-service-on-off program as a substitute for
chkconfig's bonus features.
