bfs: remove the filesystem

I agree.

At the moment, I don't.  Nowhere in this thread does anyone mention what
someone with a B(oot)FS filesystem image should do if they want to
extract whatever's stored in the filesystem.  Are there userspace tools
for that purpose (ala efs)?  Does "binwalk -e $bfs_image" suffice for
that purpose?  Or is there solid evidence that there isn't even a single
user (ala freevxfs) who strongly wants it to stay in?

BFS was only ever used for boot partitions of some old unix clone (see
Tigran's initial reply). I have hard time imagining someone has some data
on such partition he wants to still read. And if such exceptional case
arises, I agree that just using old kernel in UML / VM is a viable
alternative.

I'm all for getting rid of old cruft but there still needs to be a
documented offramp for users.

Yes, I agree that it would be good to document this approach.
