Yes, i know this workaround. That's what i use now on my acl-patched
2.2.21 kernel. But if you restore (some) files from incremental backup,
you also have to restore the acls.txt which contains the acl's of ALL
files - maybe in the meantime some acl's of files which are not part
of the restore process have changed ... so you have to apply a filter
to acls.txt to only setfacl the acl's for the restored files. acls.txt
contains multiple lines per file - so the filter isn't a simple 
on-line "grep" or so, it must be a more advanced script.

Don't understand me wrong, of course this is all solvable. But IMHO
there should be a clean standard solution without need for hacking around
for such a elementary problem in a professional server system like
Redhat AS 3.
