With a new OS, means a new first boot script that needs to be created.
Out of curiosity, I was wondering how does one go about that? I know people will post theirs as time gets closer to release date (a HUGE THANK YOU to those that do), but I guess I'm looking for tips and tricks for doing my own (and by that I mean modifying an existing one with updated commands and removing the ones that break things). What's the easiest way to determine what needs to be changed/removed/added?
