I would have to ask Shuah but am open to it. But a quick search turns up
this: https://github.com/redcap97/fuse-mfs . I would have to see if it
actually works and it does not seem to support v1, v2 of minix fs either.
There might also be a licensing issue.

One question I would have about this is that if we move minix, for
instance, out of the kernel code, how can we be sure that it is
maintained. What if some Github repo suddenly disappears? Like I said,
I would be fine with helping maintain minix, otherwise what should be
the course of action from here? What demands do we place on a userland
replacement for minix before I submit a patch to deprecate and remove
the code?

Thanks,
Jori.

PS. Sorry for sending this twice. I am still having to remind myself to
"reply all". My apologies.
