| ## Reboot delay | |||
| Some systems might want to perform actinos before a reboot occurs. These systems can watch the [semaphore](#semaphore) in `etcd` for changes to the `holders` and then do any tasks (e.g. pulling machines out of worker pools, load-balancers) necessary. Using `LOCKSMITHD_REBOOT_DELAY` environment variable grants the system time to perform these actions before the machine reboots. | |||
|
@iderdik we put up some draft docs on an alternative way to do this. Would love your help testing it. |
