Re: about GNU Hurd

[Alfred M. Szmidt]

       This depends on what issues you are refering to.  The two
       (semi-serious) problems that Marcus pointed out wrt to passive
       translators and firmlinks can be solved.  As was pointed out by
       Bushenell, and someone else.

   I would like to see these solutions.
   Could someone please show them to me?

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.   

The problem with sub-hurd's was that they provided a very secure
enviroment, and that you could not share devices between the sub-hurd
and the currently running system.  The purposed solution for that was
to have a special way to selectivley open holes (much like a network
firewall) to the underlying system.
