In any case, the *right* answer isn't to play whack-a-mole fixing /tmp races, what you should be doing is using pam_namespace or similar so each user gets their own /tmp namespace.
That would result in counterintuitive behavior, I suppose... /tmp is a fairly stupid and largely unnecessary artifact of the old. If you are in charge of a distro, it would not hurt to nuke it altogether and change all packages in your control to use per-user $TMPDIR. Some third-party stuff will break - but it breaks every now and then anyway. /mz _______________________________________________ Full-Disclosure - We believe in it.
