If I understood Matt correctly his problem is, he has already done 'request
system software add', which stores the config somewhere to be used after
upgrade and further commits will not be included in that.
He'd like to make changes to the configs before reloading the boxes and ensure
the config changes are included.

I've been quite annoyed by this, since it means you have to be awake in
maintenance window 30min-1h longer than you should, because you can't pre-load
the new software then in maintenace window just boot.

I guess most people from IOS world used to copy software in office hours,
setup boot variable etc. Then in maint window just do 'reload', this is not
viable process in JunOS world. And I'd like to hear answer to Matt's problem
