Nice script, but I don't think such a script is very useful since the order of
the daemons array is important. So it's better to use an editor I guess ;-)
Yes, this script is just appending, which is OK for most services you add.
Implementing order should be easy -> this is left to the reader ;)

I can do the reordering thing. It's not hard. But I would require a
default list of how the ordering should be. If anyone can provide a list
of all the daemons that Archlinux ships and their correct order, I would
much appreciate this.
Unlike other distros, Arch Linux doesn't have dependency information
encoded in init scripts.
I couldn't resist. So I extended my script (inspired by 'chkconfig') do
enable/disable
services and allow ordering:
Usage: daemons.sh [-b daemon] add|remove|enable|disable daemon [daemon]...
If you want to add iptables before network:
daemons.sh -b network add iptables
If you want to disable iptables
daemons.sh disable iptables
Jürgen
talk about not being able to resist :)
I had this service script i've been using forever on my various arch
boxes that does 'service start|restart|status' on /etc/rc.d/foobar.
I've merged in Jurgen's daemons.sh, so this is now much more usefull.
MiniHelp :P
- Just running 'service' will give you a list of all 'running' services
- Running service -a, will give you a list of all services (heh!)
- Running 'service foobar start|restart|status' will do what you expect :)
- Add running 'service foobar enable|disable|add|remove' will also do
what you expect.
- Running 'service -b frumpel foobar add, will add service foobar to
the DAEMONS array before service frumpel
BUG: This doesn't work well with 'background' services... if someone
doesn't beat me to it, i'll extend it to properly support background
services (the @foobar variety i mean)
hehe... nice work Jurgen
Cheers,
Essien
