Gee, goten morgen to you too; wie geht's? :-/

Hmmm.  Lemme think out loud here...

	pkg_upgrade [-p] old-pkg new-pkg
		copy old-pkg-required-by to a tmp file
		move all old-pkg stuff aside
		if (install all new-pkg stuff)
		    if (!preserve)
		    	blow away old stuff
		    else
		    	report where old stuff has moved to
		    copy tmp-old-pkg-required-by new-pkg-required-by
		else
		    delete-new-stuff
		    restore-old-stuff

Did I miss anything (outside of the obvious check for disk space)?
(This could theoretically even be written in perl.)

Yeah, yeah, "Oh, good, you volunteered to write this!"
"Yes, in my Copious Spare Time [tm]!"

If someone else wants to run with this ball, that'd be great.  Otherwise,
when I get some free time, if I can figure this stuff out, I'll do it
myself.

The hard part is going to be analysing the flow of information into the 
pkg dbs.
