Value for hidepid option
The hidepid mount option is applicable to /proc and is used to control who can access the information in /proc/[pid] directories. The option can have one of the following values: 0: Everybody may access all /proc/[pid] directories. 1: Users may not access files and subdirectories inside any /proc/[pid] directories but their own. The /proc/[pid] directories themselves remain visible. 2: Same as for mode 1, but in addition the /proc/[pid] directories belonging to other users become invisible.
