I'm trying to set up a really simple local repo. I want to have a basic repo with two versions of only one rpm, so I did:

mkdir /packages/x64

copy two rpms to /packages/x64

[root@repo x64]# createrepo --verbose /packages/x64
1/2 - jre-6u37-linux-amd64.rpm
2/2 - jre-7u9-linux-x64.rpm

Saving Primary metadata Saving file lists metadata Saving other metadata

Added the repo to /etc/yum.repos.d/local.repo

But when I do:

[root@repo x64]# yum list jre

I get:

Loaded plugins: fastestmirror, security
Loading mirror speeds from cached hostfile
Available Packages
jre.x86_64  1.7.0_09-fcs  local

ie it only shows the latest version. I know that they're both in the repo because I've run this:

[root@repo x64]# rpm -qp jre-6u37-linux-amd64.rpm
jre-1.6.0_37-fcs.x86_64
[root@repo x64]# rpm -qp jre-7u9-linux-x64.rpm 
jre-1.7.0_09-fcs.x86_64

and when I remove the latter version, and run createrepo again, the former shows up. Most puzzling, what am I missing?
