[Haskell-beginners] using HS to writing/managing a selfmade filesystem on a real partition?

[Silent Leaf]

Mostly all in the title.

I have a project of developing a personal filesystem, possibly at first
virtual (the file(s) representing a virtual partition formatted with my
filesystem, would be saved in a host filesys, eg ext4 or whatever), but
probably in the end not virtual, directly working on the contents of a real
partition.

Can haskell do that kind of thing, aka writing data on a partition directly
(without using a known filesys), etc? Is it at least more or less adapted
for this task (not talking about performances, unless the consequences be a
*really* slow filesys), aka doable, easily doable, relatively speaking (aka
not worse than with another language)?
Incidentally, if i wanted Linux to recognize the filesys, i've heard one
has to write a module and put it in connection with the kernel or
something. could haskell do that?

if that's a "no" somewhere for one of my questions, which parts can't be
written in haskell (without horrible performances or code very very hard to
write), and can they be written in C (or whatever) as foreign functions?
which parts would that represent for the whole program?

Thanks a lot in advance!

PS: just in case, tips on sources of information on how to do any of the
above will be extremely appreciated! (even if it's in, say C, for that
matter, providing there's a way to translate the steps into a haskell
program)
