irregardless of what LFS is or isn't, breaking it on the branch is
not acceptable.  you might not use it or trust it, but there are
people who do -- the people who maintain it -- and the same argument
applies equally to their work as to any other work.

this is for a change that i'm not even convinced is a good thing,
let alone deserves to invade changing the buffer cache so close to
a release.


more generally on this issue:

i don't think it matters if netbsd-6 and -current end up having
non-trivially different implementations of this code.  what matters
most is that we (a) release netbsd-6 soon and (b) keep it stable.

if non-trivial changes are necessary for ffsv2 extattr support to
be part of netbsd-6 then i think that those changes have missed the
boat.  if those changes can be kept localised, but not entirely
clean, then netbsd-6 can still have the feature without the
potential for disrupting the release.
