I assume you mean simply removing the /dev/shm link, but leaving tmpfs mounted on /tmp, and that you mean /compat/linux/proc/mounts. If I do that, I get the "error 38" again. Both proc and linproc are mounted and tmpfs is in proc/mounts: FreeBSD manatee.acadix bacon ~ 401: df Filesystem Size Used Avail Capacity Mounted on /dev/ada0p3 447G 17G 394G 4% / devfs 1.0K 1.0K 0B 100% /dev procfs 4.0K 4.0K 0B 100% /proc linprocfs 4.0K 4.0K 0B 100% /compat/linux/proc tmpfs 4.7G 16K 4.7G 0% /tmp sculpin:/usr 222G 162G 42G 79% /.amd_mnt/sculpin/host FreeBSD manatee.acadix bacon ~ 402: more /compat/linux/proc/mounts /dev/ada0p3 / ufs rw 0 0 devfs /dev devfs rw 0 0 proc /proc proc rw 0 0 tmpfs /tmp tmpfs rw 0 0 pid678@manatee:/host /host nfs rw 0 0 pid678@manatee:/net /net nfs rw 0 0 sculpin:/usr /.amd_mnt/sculpin/host nfs rw 0 0 Happy New Year, JB -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Jason W.
