Change group of a /proc file upon startup in Debian

Hello.

I was wandering where to find a place (deamon) which will assign a specific group to a /proc file (say bar group to file /proc/foo for example) upon startup.

I know I can make a simple shell script which will do

Code:

chgrp bar /proc/foo

and place it in /etc/init.d or so, but I want to do this right.

I'm used to do things the Debian way, if you know what I mean.

Is there a specific place where I can setup this kind of things?

Thanks in advance.

Why would you need that? There's probably a better way to solve your problem, as the /proc dir is 'virtual' (as in: there is no real data in it, it's all kernel stuff) and therefor rather fluid. One solution is a sym-link:

Code:

ln -s /proc/foo /tmp/foo

Thanks for reply Dutch Master!

I want to allow users from a group to have write access to a specific /proc file.

Linking to a proc file isn't the solution here, because user still needs to have write permission to a file that link points to.
