Comment # 9 on bug 1016313 from Michael Woski

(In reply to Franck Bui from comment #8)
Hi Franck,

sorry for the long delay. Meanwhile I was able to test your packages, but the
whole thing didn't work as intended, I guess. systemd seems to kill the process
straightaway, so there's no systemd-timesyncd process to attach to. I had this
problem as well when I tried to start gdb directly from a script.
Could it be that this is not really a problem with the service in question but
with systemd itself? Whenever a unit file has that @mount parameter systemd
denies executing the service?

bye Michi
