## Overview During https://gitlab.com/gitlab-com/gl-infra/production/-/issues/3872 we have to run [graceful shutdown](https://gitlab.com/gitlab-com/runbooks/-/blob/master/docs/ci-runners/linux/graceful-shutdown.md#how-to-stop-or-restart-runner-managers-vm-with-graceful-shutdown). Where we run `sudo /root/runner_upgrade.sh stop_and_poweroff` which stops the service. After the VM is booted we have to run `sudo /root/runner_upgrade.sh update` which runs `chef-client` but this fails with the following : ``` gitlab-runner.service doesn't exist ``` To fix this we would need to run `apt-get install --reinstall gitlab-runner=13.9.0-rc2` ## Root cause This comes from [gitlab-runner uninstall](https://gitlab.com/gitlab-cookbooks/cookbook-wrapper-gitlab-runner/-/blob/5e7acd6d8925f50e4909efb24b45993237b608fb/files/default/runner_upgrade.sh#L25-26) that is part of the `stop` CLI. So when the VM reboots `gitlab-runner` doesn't automatically start. ## Proposal Change https://gitlab.com/gitlab-cookbooks/cookbook-wrapper-gitlab-runner/-/blob/5e7acd6d8925f50e4909efb24b45993237b608fb/files/default/runner_upgrade.sh#L25-26 to be `sudo systemctl disable gitlab-runner` instead so the service is disabled by not uninstalled. /cc @tmaczukin @igorwwwwwwwwwwwwwwwwwwww
