[lug] Access control lists

[Terry Branaman]

I am trying to set up an ACL on a file, but I get the following:

# setfacl -m mask:7 foo
setfacl: foo: Operation not supported

I am running Mandrake 9.0, and have installed
libacl1-2.0.11-1mdk.i586.rpm, libattr1-2.0.8-1mdk.i586.rpm,
acl-2.0.11-1mdk.i586.rpm, and attr-2.0.8-1mdk.i586.rpm. The file is on
an ext3 partition.

What am I missing? Is there something else that I need to install? Or
how to I enable ACLs? I haven't been able to find any HOWTOs on this.

Thanks,
Terry Branaman
