Works well enough for me with --installroot. The host's value of
%_dbpath is now used consistently by rpm and yum. The rpmdb is
created/updated inside installroot under this directory. Packages are
unpacked into installroot. Subsequent rpm/yum commands with the same
installroot access the rpmdb at the correct path.

Chroot into the installroot, yeah you may have some minor
configuration issues to work out, but ATM I am only looking at
installing/updating the chroot from the host.

If you can suggest specific things that may break I'm willing to test them out.

In 3.2.25 yum only accessed rpmdb through the rpm module, which
consistently uses %_dbpath.

I agree it's best to have everything together under /var/lib, and this
doesn't change that default. This change just makes yum aware of the
fact that rpm can configure its database to be anywhere, just like yum
can point persistdir anywhere.
