Just finished listening to episode 102 of the Mac Admins Podcast. The guest, Armin Briegel mentioned a handy app named Erase & Install. The app is a wrapper around the startosinstall command. It's very user friendly and can detect a macOS installer anywhere on the machine. If anyone is looking for an alternative to startosinstall in Self Service this is a great solution.

I just wish with the limited space available on current model macs (that our school buys) and the size of current OS installers there was a way these could be created without having to cache or download a full installer on users machines. Like a way to use the recovery drive. Just complaining for the sake of complaining.
