Subject: [PATCH] core: limit service-watchdogs=no to actual "watchdog"
|
|
commands
|
|
|
|
The setting is now only looked at when considering an action for a job timeout
|
|
or unit start limit. It is ignored for ctrl-alt-del, SuccessAction, SuccessFailure.
|
|
|
|
v2: turn the parameter into a flag field
|
|
v3: rename Options to Flags
|
|
(cherry picked from commit 1710d4beff6329cf6ae0767953cad09593517b2a)
