I hate email sometimes. My attitude is "some things you really can't cut out". I really am all for trying to cut things out, it's just that some things are tied in rather well (like sysfs and root device as opposed to the static table before). > You may very well be right that other subsystems offer better > gain/pain, and I'm all for attacking the low-hanging-fruit first. > > > To what end?

Power Management? What does that have to do with anything?] Power Management, sysfs plays / will play a role in finding out the order in which devices get powered down. This is important on some types of embedded devices (and arguably important everywhere). -- Tom Rini http://gate.crashing.org/~trini/
