On some diskless 4.x systems, I've got the following patch in place to
let me do things before and after rc.diskless2 does it's stuff:

In practice, I use rc.diskless2_pre to do some checks to make sure the
system's disk is partitioned the way I want it, fix it if it's isn't,
and mount /var so diskless2 won't make a new one that "mount -a" will
immedialy hide. rc.diskless2_post is used to populate /var with
non-standard things. What's the right way to do this in the rc.d world?

It seems like I could add more scripts which will run before and after
rc.d/diskless, but I don't understand rc.d all that well.

Thanks,
Brooks
