BindsTo=
Configures requirement dependencies, very similar in style to
- Requires=. However, this dependency type is stronger: in addition to the effect of
- Requires= it declares that if the unit bound to is stopped, this unit will be stopped
- too. This means a unit bound to another unit that suddenly enters inactive state will be stopped too.
+ Requires=. However, this dependency type is stronger: in addition to the effects of
+ Requires=, which already stops (or restarts) the configuring unit when a listed unit is
+ explicitly stopped (or restared), it also does so when a listed unit stops unexpectedly (which includes when it
+ fails).
Units can suddenly, unexpectedly enter inactive state for different reasons: the main process of a service unit
might terminate on its own choice, the backing device of a device unit might be unplugged or the mount point of
a mount unit might be unmounted without involvement of the system and service manager.
