Indeed, I got fooled by looking at the call to opkg_install_pkg(pkg, 1)

So it is. Slightly more work than my trivial opkg patch, but then again, 
my trivial opkg patch is not much use ;-) Please disregard it.

To be honest, I have not tested the opkg "upgrade" patch in isolation. I 
have tested the opkg patch for multiple package upgrade case together 
with my changes to update-rc.d.bbclass changes (i.e. the entire patch I 
posted to the oe-core list) and this has solved the problems that I 
encountered initially. The "fix" for my use case is due to the changes 
in the way the prerm, postrm and postinst scripts work, but reviewing 
those changes, that's not good enough either.

Thanks for the review.

I'll try again later...
