Restrict access to process information to the owning user. Enabling
|
|
this option implies, among other things, that command-line arguments
|
|
remain private. This option is recommended for most systems, unless
|
|
there's a legitimate reason for allowing unprivileged users to inspect
|
|
the process information of other users.
|
|
|
|
Members of the group "proc" are exempt from process information hiding.
|
|
To allow a service to run without process information hiding, add "proc"
|
|
to its supplementary groups via
|
|
<option>systemd.services.<name?>.serviceConfig.SupplementaryGroups</option>.
