The current versionn in fedora is quite old and doesn;t have features (like the -m) switch that are very useful for dealing with gerrit repositiories. Please update asap.
I already have 1.22 built in F20, availabe in Koji. It would be trivial to backport, the changes to the spec files are minot. Unfortunately, I have to go on a special trip for a week right now, so timing is not right for "ASAP". Can you survive for a week by pulling SRPM from Koji and rebuilding?
