Unfortunately that is what I have mentioned in the patch 0. The main
problem is that the fsadm is one file script and while adding other
functionality I was building helpers and yes also changing other parts
of the code.

It was not possible for me make one feature, be done with it and move to
the another feature. Some of them actually supports each other and not
having to rebase with every change made my work significantly easier. So
at this point I am not going to rework the patches, since it would take
more time that actually write that code :).

But, since it is a single file script, and I changed the whole thing
significantly (there is not much left from the original code) I can
create one big patch covering all the new features, so it will be easier
for you to review it. Will that be acceptable for you ?

Thanks!
