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.
