Hello,

The recent update of the transmission PPA package from
2.92-1ubuntu1~16.104.2 to 2.93-1ubuntu1~16.04.1ubuntu1 has introduced a
regression that prevents the transmission-daemon package from starting up
properly in systemd systems.

Expected Behavior:
1. Start the daemon: sudo systemctl start transmission-daemon
2. Daemon takes a few seconds, then starts as described by the settings file
3. systemctl returns to prompt.

Actual Behavior:
Default:
1. Starting the daemon immediately fails
If user is corrected in .service file:
1. Startup works as expected, but systemctl holds stdin waiting for startup
to finish
2. some time later the daemon is terminated by systemd.

Diagnosis:
1. The systemd username for the upgraded package changes the system user
from 'debian-transmission' to 'transmission'
2. Some behavior fails to properly indicate to systemd (via inotify) when
the daemon has started, and the daemon is automatically terminated by
systemd after a short period of time. During the period after starting
until the daemon is terminated the software functions as expected if the
username in the systemd service file is corrected.

While I'm reporting this for 16.04, the regression looks like it has made
it's way into the 17.10 package as well.


Startup log for default behavior follows:
