Not much, but that's not the point. yum is just a bandaid that tries to
cover an ever-expanding, stagnating wound.

Yes. That's the point. The rpm-based infrastructure is bursting at the
seems.

No.

Yes, and we have a Berkeley-DB package database, that is prone to
corruption.
But the flip side of the coin is that if you keep the package repository
metadata in flat files, it's going to take forever for simple
install/uninstall transactions to get done. If you think yum is slow now,
try to drive it off flat files…
Generally, storing package repository in some kind of a lightweight database
is the right idea. It's the actual implementation that we have here, that's
the problem.
