github-runner service fails to start after a reboot

[sandydoo]

After a reboot, the systemd service fails to change to the working directory:

Jun 18 14:19:42 linux (igure.sh)[1451]: github-runner-cachix-x86_64-linux.service: Changing to the requested working directory failed: Permission denied
Jun 18 14:19:42 linux systemd[1]: github-runner-cachix-x86_64-linux.service: Control process exited, code=exited, status=200/CHDIR
Jun 18 14:19:42 linux systemd[1]: github-runner-cachix-x86_64-linux.service: Failed with result 'exit-code'.
Jun 18 14:19:42 linux systemd[1]: Failed to start GitHub Actions runner.

This can be fixed by:

rm -rf /run/github-runner
systemctl restart github-runner-cachix-x86_64-linux.service

After rebooting, /run/github-runner is empty and owned by root.
After deleting and restarting the services:

> ls -l /run/github-runner/
total 0
