I replaced all packages with ELF ones as well, but I was able to keep the
machines *running* (several of these were multiuser boxes with important
server daemons in /usr/pkg!) while doing the upgrade, rather than shutting
down the system to wait for a piss-slow rebuild of the whole shebang.

This was the whole point of moving the old /usr/pkg as a unit:  you end up
with the old stuff still available and runnable while preparing the new,
upgraded versions.
