Ok, I'll prepare a patch that enables async and disables -M. We should also document the fact that tmpmfs="YES" and varmfs="YES" in rc.conf may require the presence of at least one swap device by default, and point the users to -M with a warning if they run FreeBSD without a swap device but still want to use tmpmfs or varmfs :)Received on Thu Jun 01 2006 - 19:33:30 UTC
