I've no complaints with mandating that ebuilds can rely on second
level resolution- it's a valid gurantee as far as I'm concerned.
Further any fs that can't offer it involves the user doing something
seriously wonky, thus their problem if the ebuild horks.
If/when the major filesystems out there all do NS level resolution,
and are in common deployment, I'd have no arguement extending the
spec to mandating NS level resolution. I've serious problems w/
mandating NS resolution in PMS prior to that however.
