If you setup an empty BE LiveUpgrade simply updates its internal
records and probably does some checks to see wheather the filesystems
specified exist and that there are no conflicts.
You simply use the -J -j options to tell Live Upgrade the location
where the FlashArchive resides.
I've only used the -J option like this: -J "archive_location
nfs://<server>/<your_path_here>/archive.flar"
You could use "-j <profile>" where <profile> would be a JumpStart
profile file containing the "archive_location" keyword.

If you use the "-j <profile>" option the only thing used from the
profile is the "archive_location" entry. The file system layout in the
profile does *not* matter.
The file system layout is specified with "-m" options, when you run
lucreate.
For what Live Upgrade is concerned with, using "-j" or "-J" option is
equivalent. The "-J" option is probably provided for conveniency so
you don't need to type the Flash archive location manually if you
already have a JumpStart profile using the same archive.

I don't know the details. I think, among others, some init scripts
are created/modified.
