I wanna learn how to make my own installation media and allow for a Live USB for a custom linux distribution.

Anyone know how to do that?

...it's a skillset all onto its own.

(note: I've been using FAI but that ain't proper. I want to make it like a Debian or Ubuntu or Mint or Elementary installation ISO where it has a Live option as well as proper installation options like full disk encryption, keyboard layout, etc.)
