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)
