Description
Sending SIGTERM to the coder server is supposed to trigger a graceful shutdown that drains build jobs before exiting. However, it seems like when a build job is running at the time SIGTERM is received, the job gets interrupted anyway:

This was a result of configuring systemd to send the coder server SIGTERM and wait 10 minutes before following up with a kill signal. Howver, the interrupt and "Stopping operation..." log message appears to be immediate. The provider log also showed that its operation was cancelled partway through.
KillSignal=SIGTERM
SendSIGKILL=yes
TimeoutStopSec=10min
