Our "first timer" doesnt' realize that Plan 9 defaults to "terminal  
mode" on install.

The reasoning behind this "easy access to files" is that you  
shouldn't be keeping your
files on a local machine.  Plan 9 was designed for grids with I/O  
nodes that have some
physical security.  While you "can" run most anything you want in  
terminal mode it's not
the originally intended configuration for the OS.

I still like this model better, there is no root user, though there  
is a filesystem owner
which I guess is similar.

Personally, the first thing I do when I install plan 9 is to compile  
a cpu/fs/auth kernel
and switch to that after a bit of testing.  Then I drawterm in.  I  
can have many users but there
is still only one "owner" for those files on the system.

What I wonder about is how to make it so not just anyone can do "con / 
srv/fscons" and get full
access to the files :).

I'm still pretty new to all of this too, mainly due to sporadic spare  
time to play around with it.
