I answered that one.

And how does that solve the problem of whom to trust with mounting? Or with 
configuring a network interface? If someone has access to, say, eth0 then 
they have access to eth0. No amount of private namespaces keeps them from 
reading everything that goes through eth0, including other users' 
unencrypted traffic.

Plan 9's model says if you have physical access to a terminal there is no 
way to secure _that_ terminal against your mischief. Therefore, it totally 
trusts you _that_ terminal. However, your home computer doesn't run only a 
terminal. To be usable, it has to run at least a cpu and an auth, in 
addition to a term. Now, where is the difference between running 
authentication on the same machine as the terminal and the traditional UNIX 
way of keeping authentication/authorization databases on each machine? Or 
from Kerberos' distributed authentication model?

The directory could've been there beforehand. In any case, your deflection 
has nothing to do with the fact that Pietro Gagliardi's demand for "a few 
commands" to accomplish a certain task has been supplied with an adequate 
UNIX answer.

He's under the false impression that abstraction actually _does_ things, 
and that because Plan 9 has an everything-is-a-file model it is any more 
trivial to access a cell phone over its proprietary communication protocol 
over the cellular network. An impression perpetuated by the 9people.
