Hi "gahn".

Yes you can, by mounting a tmpfs there. fstab line:
tmpfs                   /tmp            tmpfs   rw              0       0
It uses swap space if neccessary.

But beware: TMPFS is considered to be a highly experimental feature in FreeBSD.
Well, the word "highly" is probably exaggerated, but if I remember
correctly, there are still some rough edges (sendfile? double copies
of its content? I'm not sure). I use it on my machines without
problems.

Regards

Lucius
