What are you looking for to be "better"? That key combo is essentially if you 1) don't want Munki to run right now, because you need to log in right now or 2) don't want Munki to run because it's on an install loop.
1) can be because it's literally not a good time. Maybe you don't want Munki to run at the login window at all. There's a Munki preference for that. I used to, for school lab computers, have a nopkg that set that preference during the school day and unset it before and after school, so updates could be installed without bothering students or preventing them from logging in.
2) is likely because you messed something up, so you need to figure out what you did wrong.
