Learn from minix: fork ramfs.

getting a hole-in-one with nobody around...)

So fork ramfs already.  Copy the snapshot you like as an educational
tool, call it skeletonfs.c or some such, and let the current code evolve
into something more useful.

Seems to me a dude named Andrew was in a similar situation a decade or
so back, and decided to resist all change in the name of having a clear
educational example.  Patch pressure built up past the "reimplementation
from scratch threshold event horizon thingy" (the tanenbaum-torvalds
barrier), at which point the code forked under its own weight anyway.

Saves a lot of bother to do it now, if you ask me.  You'll wind up with
a new ramfs one way or the other.  People will keep writing it as long
as it's not there.  (The whole "why climb mount everest" thing, you
know.)

I could, of course, be totally wrong about this...
