Upon boot, the server starts any number of services and service dependencies. Errors in these services’ unit files can cause the server to hang, error out, or otherwise fail to boot in a healthy state. In this lab, you’ll explore a service dependency issue that is causing problems when you attempt to run `pmcd`. _This lab is not approved or sponsored by Red Hat._
