Does anyone know out-of-the-head whether tmpfs supports ACLs - and if

I have some vague recollection that tmpfs doesn't support ACLs snd it
appears to be so...
Is there any RFE which requests the implementation of NFSv4-like ACLs
for tmpfs yet ?
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%
Ok... does that mean that I have to create a ZFS filesystem to actually
test ([1]) an application which modifies ZFS/NFSv4 ACLs or are there any
other options ?
Use function interposition.
Umpf... the matching code is linked with -Bdirect ... AFAIK I can't
interpose library functions linked with this option, right ?
I never build test harnesses with explicit ld options (I use the C or
C++ compiler for linking).
There is a note about interposition in the ld man page description of -B.
