Re: Console permissions?

[ludovic p. <pl...@nn...>]

Hello,

I wrote a small tool (session fs) to deal with issues related to sound ca=
rd &=20
multi-console : http://perso.nnx.com/pludov/homepage/index-sessionfs.html

With it, scripts which normally modify ownership of /dev/dsp should then=20
modify the files related to their DISPLAY (provided that they only=20
touch /dev/dsp and not /dev/dsp1, /dev/dsp2...)=20

But I never tested it for that purpose (I always have the same user on bo=
th=20
DISPLAY)

Basically, it replaces /dev/dsp to a symlink to a dsp depending on the DI=
SPLAY=20
environement variable (/dev/dsp1, ...).
The main goal is to hide it to common programs which generally use /dev/d=
sp.

Hope it helps !
