Sure. See, you installed a network-distributed Operating System on a single machine on which you operate locally. Think of it this way, normally you would create file-/cpu-/authservers now. You can substitude 'root' for 'hostowner', which is alias as bootes in most documents (and eve in the kernel iirc, but unsure). He is in group sys and most other groups needed to operate on almost anything (glenda is the hostowner of a single-system-installation).

Oh? I kind-of run a fileserver with an auth-server, what documents stat that?

Not. Distributed network environment, you are trying to use it like Unix, it won't really work that way.

Why not, acme rocks for that :-D

So you are demanding more(1)/less(1), there is not really such thing. If you want to read manpages, search arround in them etc, acme does a great job. If page(1) can search in postscript, and you prefer page, man(1) can assemble them.

Depends what you reconfigured. Sometimes it is a damn good idea to restart the whole OS after resetup, because you are right there - if some startup-script contains a typo, you will be able to react (unlike the system goes down unexpectedly at 1 am, murphys law, you know).

Ac97 driver for Plan9? I briefly looked into ac97*.pdf and planned to start working on it if I find the time...
