Mac OSX 10.4 now provides support for EAs

Mac OS X 10.4 now provides support in the BSD layer for the xattr
functions on HFS+ and HFS via the ._file convention [1]. Current limits
seem to be key 128 bytes, value 4 KiB. Exciting!

It should be trivial to implement this in libdar, but care might be
taken to either mask ._file on HFS or exclude support for EAs and just
copy the ._file (probably the former is better). There may also be small
differences in namespace definitions.

As for ACLs, apparently, they are masked out by the xattr API [2]. This
could be a problem, but there may be a way around this.
