'Redesigning' things to fix bugs seems to be common sense
nowadays, as if everything existing is always too bad to be

Of course the same is valid for the redesigned code base in
the future.

One interesting point is that dropping DEV_BSIZE doesn't
really mean something new but a jump backwards. That's where
we came from, that's what was 'redesigned' then.

It works fine for 16 years now. The problems only come from legacy
code and code from other sources that wasn't adapted to the then
valid design, mainly because the problems didn't show up immediately
due to lack of hardware.

The software that needs to be fixed is pretty obvious, it's
not a large rototill but if you are into 'redesigning' you
may see a lot of places (unrelated to DEV_BSIZE) that could
be structured better and cleaned up, e.g. partition handling.

And all this should be done, wether you intend to drop or
