systemd/firejail interaction

[netblue30]

From wordpress (user Robert in Basic Usage):

Experiencing problems when firejail and transmission-daemon under systemd. The daemon is started from a systemd service file. Lots of messages like this are going in system log:

Feb 19 11:28:39 megat systemd[1]: transmission-daemon.service: Got notification message from PID 18737, but reception only permitted for main PID 18734

A partial solution was to include a further line in the transmission-daemon.service file "NotifyAccess=all"

Shutdown problem: Often (but not always), transmission-daemon will segfault and, whether it segfaults or not, the shutdown hangs for at least 90 seconds until some timeout mechanism finally kills all running processes.

The system runs a very vanilla installation running under KVM/QEMU, though I doubt if that’s relevant.
