ACL and Extended Attributes in Hurd ?

Hi,

is there a way to enable ACLs and Extended Attributes in Hurd ?

I see the whole software equipment for that. Even the Linux adapter
of libisofs compiles flawlessly on Hurd.
But i cannot test it because i fail to assign ACLs or xattr to files
in my home directory:

  $ setfacl -m u::rwx,g::r-x,o::---,g:sys:rwx,u:daemon:r--,mask::rwx x
  setfacl: x: Operation not supported
  $ setfattr -n user.test_xattr -v test_value x
  setfattr: x: Operation not supported
  $

On Linux i would have to add options "acl,user_xattr" to /etc/fstab
resp. to the mount command.
I tried the /etc/fstab change with Hurd
  + /dev/hd0s1      /               ext2    acl,user_xattr  0       1
  - /dev/hd0s1      /               ext2    defaults        0       1
but there is no improvement after reboot.

I found a sparse description of translator ext2fs, but no mentioning
of ACLs or xattr.


Have a nice day :)
