Howdy,
Per discussion on -arch and the svn list about improving boot time and
stripping down the kernel to just that-which-cannot-be-modularized I
created the attached script to kldload modules that don't need to be in
loader.conf. It cut quite a bit of time off my boot, so hopefully it
will be useful to others as well.
To use it just put everything that is being _load'ed in loader.conf into
kld_list in rc.conf[.local]. For example, mine has:
kld_list='umass coretemp ichwd linux nvidia if_wpi'
If there is agreement that this is a good direction to go I'll be happy
to commit this along with the relevant /etc/defaults/rc.conf and
rc.conf.5 changes.
hth,
Doug
