Console permissions?

[Mark H. <mar...@xs...>]

Hi,


I've been running multi-console for a while now (sometimes ruby, sometimes
only with xorg patches), but would like to solve one final issue.
Normally when using a single console, the first user to login gets all 
kinds of
devices assigned, and thus is able to use /dev/cdrom for instance or the 
audio
devices /dev/dsp, /dev/mixer, /dev/snd/* and /dev/sound/*.

When multiple users being able to log in at the same time, I want this 
behaviour
to change. Simply disabling the default behaviour is possible, and thus 
setting
these devices to sane defaults is already possible.
(see 
http://www.redhat.com/docs/manuals/linux/RHL-7-Manual/ref-guide/s1-sysadmin-console-access.html 
)

However ideally, I would want the proper devices to be assigned to the 
proper
user (e.g. if user john is logged onto head1, I want /dev/dsp1 and 
/dev/mixer1
assigned ownership to john, without interfering with user jane on head2 who
has assigned /dev/dsp2 and /dev/mixer2).

Anyone have an idea how to get this done? Can I do this using the
/etc/X11/gdm/PostLogin and /etc/X11/gdm/PostSession scripts or is there
a better way?


Greetings,
Mark.
