XFS has xfsdump and xfsrestore, which apparently can be used with tools
like amanda, which does a full backup of the filesystem including ACLs.
Btw, Mandrake 8.1 and later ship XFS ACLs out thew box, with
samba-2.2.1a with ACL support. Might be a bit less work than recompiling
both the kernel and samba on Rehdat. Newer versions of samba (2.2.2, and
soon 2.2.3) for Mandrake 8.1 (with almost-out-the-box winbind support)
are avaiable at http://ranger.dnsalias.com/mandrake/samba .
