Re: about GNU Hurd

[Alfred M. Szmidt]

       The major problem was that one could use firmlinks to escape a chroot.
       The solution to that is to simply not use chroot, and use what was
       specifically designed for the task, namley sub-hurds.   

   Can you find, and show me, messages or text where this approach was
   written up in more detail?

I don't think this was ever written up, since sub-hurds have been part
of the Hurd since almost the beginning.
