# Note, wait_for_unit does not work for oneshot services that do not have RemainAfterExit=true,
# this is because a oneshot goes from inactive => activating => inactive, and never
# reaches the active state. To work around this, we create some mock target units which
# get pulled in by the oneshot units. The target units linger after activation, and hence we
# can use them to probe that a oneshot fired. It is a bit ugly, but it is the best we can do
