If only by you:(. I'd suggest you make your 5.x partition UFS1 and be
satisfied with that - that's pretty much all you can do.

If 5.x couldn't understand 4.x, that would be a bad thing. But forcing
5.x to be absolutely compatible with 4.x is another bad thing.

If you were forced to stay that compatible all the time, you wouldn't be
able to do major architectural changes. If everyone thought the same
way, an Athlon or a P4 would be a 80286, only MUCH faster (which it is
for most olden DOS or Windows/16 programs, so your definition of
`Windows way of life' is definitely contrary to mine).

You don't complain 4.x can't run 5.x binaries, do you?:)
