DISCLAIMER
|
|
|
|
This uses a somewhat hidden feature in NixOS, which is the
|
|
"runner". It's a script that's available on systemd services
|
|
that lets you run the service independently from systemd.
|
|
However, it was clearly not intended for public consumption
|
|
so please use it with care.
|
|
It does not support all features of systemd so you are on
|
|
your own if you use it in production.
|
|
|
|
One known issue is that the script does not respond to docker's
|
|
SIGTERM shutdown signal.
