SetUnitControlGroup is removed in systemd git.


SetUnitControlGroup is not documented, for this reason.

The mode parameter of StartUnit() is documented here:

This is generated as soon as the unit is garbage collected, which will
happen a short while after a unit is stopped and no longer
referenced. There is no nice way to force this immediately.

It's the enablement state of the unit file. It's one of "enabled",
"enabled-runtime", "linked", "linked-rutime", "masked",
"masked-runtime", "static", "disabled.
