...but this is by design - if the versionlock plugin is enabled it will
refuse to do anything at all unless a versionlock list can be found. The
rationale is that if you care enough about package versions to use
versionlock plugin, you don't want a config file gone missing (or
unreachable due to network break etc) mean that the system can be
updated to any available package versions. So it needs to stop.

The fix is to either 'rpm -e yum-versionlock' if you don't use it or to
provide the missing config file.

So the hell frozen over already god knows how many times :) Didn't
remember that, possibly because it doesn't actually downgrade the
package if already installed to meet the requirement. Anyway, that seems
to work as well with --allow-downgrade now.
