I noticed that in my lenny distributions of debian that the proc files are read all in that any user can see if a process is running. In squeeze I noticed that the proc files are readable just to that user.
For example the root processes are not visible to users in squeeze but they are in lenny. I didn't setup our lenny servers but is there something that was done that caused lenny (either by me predicessor or something actually different in the distribution) to make the procs visible to all?
Note: I took a look at the fstab and they are the same for proc in squeeze and lenny.
