That unfortunately confuses me more... I thought I understood it and
then I tried an experiment...

I created a local repo with the following packages:
gerrard-first-1.0-1.noarch : Toets rpm vir myself
gerrard-first-1.0-2.noarch : Toets rpm vir myself
gerrard-first-1.0-3.noarch : Toets rpm vir myself
gerrard-first-1.0-4.noarch : Toets rpm vir myself
gerrard-first-1.1-4.noarch : Toets rpm vir myself
gerrard-first-2.1-0.noarch : Toets rpm vir myself

After reading your reply I thought that versionlock could be described
as a "list limiter" in other words if I have the following packages in
versionlock.list
0:gerrard-first-2.1-0
0:gerrard-first-1.1-4

then only those packages will show when I do a yum search gerrard
--showduplicates

That is not the case and I still get a full listing.

I have tested this on Centos 5.4 with the
yum-versionlock-1.1.16-13.el5.centos plugin
I also manually installed the latest versionlock plugin as detailed in
the FAQ but  I get errors when doing any yum operation then...
When I rewrote the FAQ I could lock files using the latest pluging
without errors so maybe my "basic" package is a bit buggy... if fact I
did some more testing(while writing email) and versionlock does not
behave as expected with my package.

Is there a test package/test repo that I can use for
testing/experiments? I scanned through the git trees and could not see
anything obviously named.

The error I get is:
