+ The config option toggles if a task setting its loginuid requires
+ CAP_SYS_AUDITCONTROL or if that task should require no special permissions
+ but should instead only allow setting its loginuid if it was never
+ previously set. On systems which use systemd or a similar central
+ process to restart login services this should be set to true. On older
+ systems in which an admin would typically have to directly stop and
+ start processes this should be set to false. Setting this to true allows
+ one to drop potentially dangerous capabilites from the login tasks,
+ but may not be backwards compatible with older init systems.
