On a multi-user server (and that includes web access like PHP or CGI),
you really don't want user-writable directories on a filesystem with
anything important, especially security-sensitive things like setuid
binaries. Hard-link tricks are evil. I run with a separate /tmp
(usually tmpfs now) and bind mount it to /var/tmp as well.
Not to get too far off into the weeds but Polyinstantianed tmpdir
(pam_namespace) are a good idea here. Everyone gets their on /tmp
and /var/tmp and no one else can see them.
