After https://docs.theforeman.org/3.15/Managing_Hosts/index-katello.html#remote-execution-jobs-for-image-mode-hosts, include a concept that explains how packages installed on image mode hosts after boot-up are transient and get removed at reboot. Show a procedure for finding the persistence on a host (in the content tab) and how to generate the Containerfile command for installing select transient packages the next time they rebuild the image mode host.

In the dev draft, propose a title for the concept module and the procedure.
