This is definitely NACK by me. I do not like this and there are
several reasons why.
First of all the name. Given the history of ext file system we tend
to increase then number with the new version of file system. However
you're saying that this is just for testing features ... in that
case it does not make any sense to call it ext5, but not just that
it's stupid to call it ext5 especially since we might actually want
to release ext5 in the future and this would be really confusing for
everybody involved.
I've been trying to get rid of the ext4dev bits and pieces
more-or-less successfully and you're adding new type once again. We
might start the discussion whether to revive ext4dev for this kind
of thing but I am not really convinced that this is the right way to
go either.
What about just simply using mkefs.conf to specify the feature set
we want and use that ? It's simple enough and it should work. We
could also extend the configuration to be able to set default
mount options and such if that's not possible. I just do not understand
why to introduce new file system type if that's just for testing
ext4 features.
Thanks!
