i meant something along the lines of "verbatim and interoperable
copies" of filesystems from other operating systems vs. the stuff like
ffs or lfs or ufs (or whatever you call it) that "came with" netbsd.

yep, and admirably so.  :)

well...i'll beg the minor nit that they have the most "support" and if
was setting up a new box, i certainly wouldn't pick ext2fs as my root
filesystem format, with ntfs for /usr and adosfs for /usr/local.  i'm
gonna pick something that's "native".

which is probably about as effective as claiming that netbsd is unix.

i'm just wondering about the implications.  do they all completely and
totally interoperate?  when was the last time you booted netbsd from
an ntfs or ext2fs (or even lfs) slice?
