That are great news. IMHO tweaking the xattr-related options would be 
good. The portablity problems even between different linux kernel 
versions of File capatibilies lead me to the point that I'd like to 
archive only user.* xattrs, and security.* xattrs iff a specific xattr 
handler is available (e. g. for ACLs we have one, and for Capabilities 
there is my patch available for handling them).

So adjusting the options would be good, perhaps

--acls                Will archive .what it currently does
--acls=user           Only user.*
--acls=wellknown       Only user..*, security.*.
--acls=all             Will archive all acls, should imply acls-include. 
Those being handled separately should not being archived as xattr
            (extracting them might overwrite a correctly restored entry 
by a wrong one, e. g. UIDs changed).


Gven that is point has not been discussed in public, my patch does not 
propose a ready to use options handling.
