this is pretty much the same on any distro - including linux 1 (or 2 or
3 etc.) in grub/lilo boot
SysV is just more comprehensive. Confusing if you've learned to
manhandle things and simple when you get the idea and the tools.
chkconfig takes advantage of all 'services' by the fact that the startup
script would have the 'numerical' equivalent of where the
daemons/services order in both starting and killing as well as xinetd
stuff such as ipop3, imap, etc.
consider...

now you can edit things by hand but why bother?
# chkconfig --list saslauthd
saslauthd 0:off 1:off 2:off 3:off 4:off 5:off 6:off
# chkconfig --levels 2345 saslauthd on
would turn it on in those run levels
# chkconfig saslauthd on
would turn it on in all run levels indicated in the SysV script or if
not indicated, all run levels
and beyond the normal daemons...there's the xinetd services...
# chkconfig imaps on
would set disable=no and restarts xinetd
It's a very nice tool - I don't usually bother editing anything
inside /etc/init.d or /etc/xinetd.d by hand (links or otherwise)
