Well, for one thing, how do you define "cpio archive", each with its own
.xattr-list file? Second, that would seem to depend on the ordering, no,
in which case you depend critically on .xattr-list file following the
files, which most archivers won't do.
Either way it seems cleaner to have this per file; especially if/as it
can be done without actually mucking up the format.
I need to run, but I'll post a more detailed explanation of what I did
in a little bit.
