Did anyone thought about creating a framework and drivers to allow

another Solaris instance, similar to UsermodeLinux? This would be

web hosting, too.
While this is somewhat true, the Solaris kernel debugging framework
is so far advanced compared to that on Linux, that a user mode
process does not offer that much extra. The most difficult to debug
are hangs which cannot be examined in the kernel debugger; typically,
a usermode kernel does not run at such a low level so such hangs
would not be reproducible.
It would still make development of some parts of the kernel easier
(for example: file systems. My attempts to get reiserfs ported are not
very fruitfully as each panic-reset-test-recompile-boot-panic cycle
takes ages on this old Ultra5). First at all you don't need a separate
box and *physical* access - you just run the process and that's it
(then I could use a V890 here instead of this lame Ultra5).
Can you use a zone for this testing?
