[gentoo-user] Dynamic service runlevel

Hi geeks,

Is it possible to set dynamic service run-level (rc-update) according to
different kernel version.

There are different kernel versions in my grub menu, and I need to switch
between these versions for development purpose. I currently want to disable
some services under specific kernel version., but I cannot find where to
customize this. Any suggestion?

Best wishes!
Linlin

What I have done is to have two different runlevels (default and kde in
my case) with different services added to each one (the kde runlevel
starts X, kde, and som other stuff that I do not have in the default
level). Then I have added "softlevel=kde" to the parameters for the kernel.

Hi Dan,

Thank you very much! That is very helpful.

What if I want to change the behaviour of "sysinit" runlevel? Where
can I change it to another new runlevel for specific kernel version?

BTW, the services I want to disable is udev{,-mount} for kernel-2.16.31.

Sorry, I can not help you there.
