how's this then: if changes are made to ext2fs (or ntfs, or any of the
"non-native" fs types), we (netbsd, that is) will have to play catch
up.  but if changes are made to ffs or lfs, that's changes that we (by
definition) already have, so there's no catch up period.

or do you think the ext2fs people will adopt features that we might
add to out ext2fs code (for example)?

of course.  :)

yes, true.  it just feels...funny.
