Re: user-mode-linux for Mach?

[Constantine Kousoulos]

Currently, uml does not support device handling from user space 
nor has been ported to any os other than linux. However, it is 
just a user space process, so i'm not pessimistic about porting it 
to the Hurd.

I'm clueless about system call interception and ptrace() in 
GNU/Hurd. Most likely, they are not supported. However, can't we 
implement something like that? I've never implemented system call 
interception before :) but the theory is not that hard to 
understand. Ptrace() seems more difficult.

All in all, uml is not a sure bet but seems very promising IMHO. 
If it works, it could provide the Hurd with a very good tool for a 
long term usage.
