If you can, your best option would be to do whatever this script does in the image itself. That way, you never need to restart any services; your image would already contain whatever the result of that script is. You can do that with a postinstall script. Pay attention to paths; the postinstall script will not run in the chroot environment. And of course do not restart any services in a postinstalls script, as it would affect the wrong system.
But sometimes that's not an option (or updating on-the-fly without reboot can be desirable). In that case, your second-best option is what you are doing: in your postscript, run systemctl restart on whatever services need to be restarted. _______________________________________________________________________ Kevin Keane | Systems Architect | University of San Diego ITS | kke...@sandiego.edu Maher Hall, 192 |5998 Alcalá Park | San Diego, CA 92110-2492 | 619.260.6859 | Text: 760-721-8339 *REMEMBER! **No one from IT at USD will ever ask to confirm or supply your password*.
