tmpmfs="YES" and going from single user to multi user mode
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, After going to single user mode and back to multi user mode on a system with tmpmfs="YES" in /etc/rc.conf, I wound up with these filesystems: trond@enterprise:~>df Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/ad0s1a 9195750 3179348 5280742 38% / devfs 1 1 0 100% /dev /dev/md0 63214 14 58144 0% /tmp procfs 4 4 0 100% /proc /dev/md1 63214 20 58138 0% /tmp There should either be a shutdown script that unmounts /tmp when tmpmfs="YES" and /tmp is indeed mounted as a MFS, or the startup script should check to see if /tmp is already mounted (as a MFS) before attempting mount the MFS (again).

You might want to ask on the freebsd-rc@ list if you need help. Good luck, Doug -- This .signature sanitized for your protection

That problem doesn't occur when you mount /tmp via /etc/fstab
instead of tmpfs="YES" in /etc/rc.conf. I always prefer to
use /etc/fstab for the above reason and others. And entry
like the following will do (for a 64 MB /tmp):
md /tmp mfs rw,nosuid,async,-s64m 0 0
