<sigh> (kicks self in head) my englihs is not too goodly today. :)
i meant to imply that under the same set of operations and uses (ie,
creating, moving and deleting a few files or something like that), the
two would be virtually indistinguishable. i could
(supposedly...although i've never tried it) use ext2fs for my
/usr/local/src and share it with linux on the same machine.
i didn't mean to imply that any code was copied at all. or "taken
verbatim". am i making more sense yet?
>And, further, our ffs is interoperable with lots of other systems
yeah...but it's the one that i consider to be netbsd. i wouldn't
think the same of ext2fs or ntfs or even lfs (since ffs has years more
functionality under its belt).

yep. i'm aware of that.

that's because i can't quite make up my mind about lfs. :)
it certainly "feels" like it ought to be "native", although i've never
used to to my satisfaction, but it's not much like anything i've seen
elsewhere. it's more "netbsd-ish" to me. more native.
