Howto control what's being restarted when changing runlevel?

Hi folks!

I've upgraded my kernel from 2.6.11-gentoo-r9 to 2.6.13-suspend-r4. When booted with the new kernel, switching runlevels causes alsasound to get restarted. Now that's no very good for me, because I switch to a battery runlevel everytime i unplug the AC adapter and stopping alsasound causes XMMS and xfce4-panel to crash (the latter has a volume control on it, that's probably why). How do I make sure that alsasound is left the way it is?

The interesting thing is that with the previous kernel "/sbin/rc battery" says only:
* Loading ALSA modules... [ok]
No unloading at all.

Any help appreciated.

For now I'm using a truly horrible workaround - a tweak of the /sbin/rc script. When switching to the battery runlevel it skips the whole service stopping section. Still hoping someone would show me how to do it properly

Runlevels - hopefully useful.

You need to have alsasound either in the boot runlevel or have it in both your default and your battery runlevels. If a service isn't in a runlevel and it isn't a boot service, it will be shut down when changing runlevels.

Thanks for your help. I have alsasound in both default and battery runlevels, also tried adding it to boot - that didn't help.
But I managed to work out what was happening. The cause was hotplug - present in default runlevel, but not in battery, so when switching it got stopped. In /etc/init.d/alsasound I had "after (...) hotplug" and that's why alsa was being restarted. I removed hotplug from there and everything works fine.
