Honestly -- I have no idea, I only had to do it a few times, on Yocto and buildroot images, and in pretty restricted cases. It was pretty easy (basically udev has this file which matches a set of device selection rules with a set of actions, effectively saying "if I encounter a device of this type, I'm going to do these particular things"), but I googled my way through it.
I expect there are some distro-specific hoops to jump through, but I have no idea which ones -- I really don't like automounting, I keep it disabled even on KDE.

(Why? Old habits die hard, I guess?)
