[Samba] re[2]: [Samba]NT ACLs and backup.

[Buchan Milne]

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 .
