gzipped tar file containing files needed to reproduce the bug
If "systemctl daemon-reload" is executed within a second of a timer expiring,
the timer will not fire and will never be rearmed. It stays in "elapsed" state
forever.
I originally see this problem in OpenSUSE-12.1 which uses systemd-37, but I
have tested this against the stock systemd-196, and the problem still exists
there.
I've included a gzipped tarfile which contains a service file
(elapsed-bug.service), a timer file (elapsed-service.timer), and a bash script
which reproduces the bug.
How to reproduce the bug:
1) install the service and timer file in /etc/systemd/system
2) modify ExecStart in the service file to log something to a file or something
of that nature (so you know the timer is running properly)
3) systemctl daemon-reload
4) systemctl enable elapsed-bug.timer
5) systemctl start elapsed-bug.timer
6) make sure the timer is running properly
7) run test1.sh (you may need to modify the awk field depending on the output
of "systemctl status elapsed-bug.service")
8) it will print out a message that it has found the bug, and then exit (may
take a minute or two)
9) verify that your printout (or whatever your ExecStart was doing) is no
longer doing it</pre>
