	Any such filesystem should be able to share the vast majority of
	FFS code, probably even down to the point of 'everything, just
	with ifdefs'.

	Hmm - why is ACL support any more 'unhealthy' than say quota
	support with options QUOTA?

	Another option might be a 'metadata' filesystem layer that could
	be mounted over any other filesystem to give ACL, MacOS 'resource
	forks' and anything else required. Keeping things in sync if
	anything ever modifies the lower filesystem without going through
	the metadata layer would be a nightmare though. Ick.
