So you assume that there never will be more than one user be logged in?
I guess having more than one user being logged in *at the same time* is
fairly uncommon. Just as ConsoleKit would remove ACL file permissions on
logging out, maybe it could remove RT prio stuff as well. I don't know
how possible this is though.
There's no need to remove a user from the group audio. There's no need
to handle this by a script.
If for a multi-user-system there shouldn't be an admin with knowledge,
it soon or later will cause issues.
One of the advantages of Linux is that the line between "single user
system" and "multi user system" is blurry. E g, I could run a web server
or other service on the same machine as I use for audio production. This
is great, it saves hardware. If a malicious user breaks in to the web
server, I don't want him to be able to use RT prio to lock down the
entire machine.
If Ubuntu Studio wants to be insecure in that sense, I guess that would
be okay (to me personally, I can't speak for Ubuntu's security team),
but I would definitely not have it in the Ubuntu by default.
