can you argument in few lines about this security model and why is
better than my proposal? and ofcourse..why its elegant, simpler and
effective, those are easy to say words but certainly i dont know plan9
that much to discuss that.

A more than 2urls reply would be more constructive for the thread.

for me the 'root' user is a simplification for a user with all priviledges
(which is not true at all, because kernel have more priviledges than root)

In hurd you have a guest user with really low priviledges which requires
no login. it is fun... but i have never find a real use case a part from
finding a file on the filesystem before login to change the bootloader

Thanks for the plan9 caps info, didnt knew that.
