The "folks at FreeBSD" who developed UFS2 is Kirk McKusick
(and others, I'm sure).  The challenge, IIRC, was that some
FreeBSD folks were hitting terrabyte arrays a couple years
ago.

Obviously, machines should handle PetaBytes or more sooner than later.

So yeah, NetBSD could suck in UFS 2 (or hell, ReiserFS).

Is there a gentle way to fork the hooks in the kernel that
use large file systems and keep the old one for those of
us who don't want to live on the cutting edge?

I'm really happy keeping my file systems really, really stable
and changes should be for those on scrap systems?

Perhaps:
#ifdef READYTODIE_FS
....
#else
	old stuff here
#endif
