Compare the damage to a non-async set. Might be better to mount /usr/obj async only, since it can always be brought to a known state w/o loss of data with newfs. /usr/src can be much harder to do that with if you have local mods... Also, mounting /usr/src async doesn't seem to buy much in the make world stone. It does help to mount /usr/src noatime, however. Warner
