Managing ACL's on device nodes

I just described a scenario wherein this is a problem. I don't know how 
likely this scenario is going to arise in the long run. Perhaps more 
importantly, I'm trying all design decision to be spelled out explicitly 
here on the mailing list, such that we can dig them up from the archives 
in the future.

Synchronously as part of login. /etc/logindevperm lists devices to be 
chmod'ed and chown-ed to that of the system console. It is very similar 
to pam_console. I can envision this changing in the foreseeable future 
to better support multiseat environments, and it not unlikely that we 
won't take advantage of the proposed permission setting capability in 
HAL (I think it is useful in general though).
