Even if it's not that long, I'm not super happy with adding some more
packages to our default build, for a use case that is normally pretty
limited.

So, if you think that specifying the capabilities or extended
attributes should be done via a separate data file, then it means we
will have a new option to specify this data file, and we could
therefore only bring the additional host-fakeroot dependencies only
when this option is enabled, no?

And possibly the above option should be made visible only when the
underlying filesystem supports extended attributes.

What do you think?
