If you do the move with a single C/C++ program rather than a shell script,
the libraries are already loaded in memory when they move, so it wouldn't be
an issue at all. Doing it with a shell script is trickier, but the UsrMove
folks actually had that working (with LD_PRELOAD tricks), before it was
decided that doing it in dracut was somehow "safer" (which sucks, because it
makes the process much less convenient than a simple script or binary to
run).

Same with the "supported" upgrade types.
