I actually got around to testing this today, and it appears to work fine
without modification. I've tested this on both a centos and fedora host
per the same instructions in the bz:

It's working fine.

No. That's an absurd workaround, not a fix. The fix (were it not
working) would be to remove the package from the base container.
