I have some vague recollection that tmpfs doesn't support ACLs snd it appears to be so...

ZFS

   opensolaris% touch /var/tmp/bar
   opensolaris% chmod A=user:lp:r:deny /var/tmp/bar
   opensolaris%

TMPFS

   opensolaris% touch /tmp/bar
   opensolaris% chmod A=user:lp:r:deny /tmp/bar
   chmod: ERROR: Failed to set ACL: Operation not supported
   opensolaris%

Does anyone know out-of-the-head whether tmpfs supports ACLs - and if
"yes" - which type(s) of ACLs (e.g. NFSv4/ZFS, old POSIX draft ACLs
etc.) are supported by tmpfs ?
