Whenever a unit is started fresh we should flush out any runtime data
from the previous cycle. We are pretty good at that already, but what so
far we missed was the ExecStart=/ExecStop=/… command exit status data.
Let's fix that, and properly flush out that stuff too.
Consider this service:
[Service]
ExecStart=/bin/sleep infinity
ExecStop=/bin/false
When this service is started, then stopped and then started again
"systemctl status" would show the ExecStop= results of the previous run
along with the ExecStart= results of the current one, which is very
confusing. With this patch this is corrected: the data is kept right
until the moment the new service cycle starts, and then flushed out.
Hence "systemctl status" in that case will only show the ExecStart=
data, but no ExecStop= data, like it should be.
This should fix part of the confusion of #9588
