It would be useful to make a precise proposal to eliminate chroot as a
mechanism and use sub-hurds to do the same job. Then people could look
for flaws in it and we could see if it really works.
I'm not sure what such a proposal would look like, or how one would
find flaws in it.
How would you build a sub-Hurd for real practical use, and
what sort of holes would be needed to make it work
in a case where you might have used chroot?
