Interesting question takes a
few minutes to test...

Let's try the new ACLs on tmpfs

[tp47...@norton:] cd /tmp
[tp47...@norton:] df .
Filesystem size   used  avail capacity  Mounted on
swap   528M    12K   528M 1%    /tmp
[tp47...@norton:] grep swap /etc/vfstab

/dev/zvol/dsk/rpool/swap    -        -        swap    -    no    -
[tp47...@norton:] 

[tp47...@norton:] touch file.3
[tp47...@norton:] ls -v file.3
-rw-r-   1 tp47565  staff  0 Sep 16 14:58 file.3
 0:user::rw-
 1:group::r--        #effective:r--
 2:mask:rwx
 3:other:---
[tp47...@norton:] 

[tp47...@norton:] chmod A+user:lp:read_data:deny file.3
chmod: ERROR: ACL type's are different
[tp47...@norton:] 

So tmpfs does not
support the new ACLs

Do I have to do the
old way as well?

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 ?

By all means, test with ZFS.  But it's easy to do that:

# mkfile 64m /zpool.file
# zpool create test /zpool.file
# zfs list
test   67.5K  27.4M18K  /test

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%

Use function interposition.  I am currently updating an ACL manipulation 
application and I use mocks for the acl get/set functions.

tmpfs does not support ACLs

see _PC_ACL_ENABLED in [f]pathconf(2).  You can query the file system 
for what type of ACLs it supports.
