The current behavior was for gitlab-runner is to immediately terminate when there was a restart required. This can lead to aborted builds and is annoying to users. By enabling graceful mode gitlab-runner will wait for all builds to finish before terminating. The disadvantage is that a nixos-rebuild switch needs to wait till all jobs are done. Because of that it is not enabled by default.
