Aside from adding the rc.conf variables there has to also be a /tmp folder in the first place. I don't know why. I would figure that if needed that that would be part of the boot scripts. But it isn't, so for us tmpmfs newbies: Create an empty /tmp folder Add the following to rc.conf: tmpmfs="YES" tmpsize="50m" tmpmfs_flags="-S -M -o noexec,nosuid" clear_tmp_enable="YES" reboot -- Wil Hatfield ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

By default it does a memory-backed disk instead of file-backed, but that can be adjusted.

Re: Partitioning on existing system
I don't see what the trouble. If you want a /tmp directory on a disk, just do : $ cd /foo# the disk you want, may be / $ mkdir /tmp Thats all. 2006/4/9, Wil Hatfield <[EMAIL PROTECTED]>: > Ok I screwed up on one of my machines and forgot to put the /tmp directory > on its own slice.
