I want Foreman also to be able to provision SLES 11.3, however after trying alot of combination/associations I'm still always having the problem that in the "Operating System" tab on the "New Host" page the Media dropdown is greyed out. The Parameters in production.log:

I'm having the impression that SuSE support has bitrotted away in the last two years, because nobody is using it. As I'm forced now to also support SuSE with my Foreman/Puppet installation, I'd really like to see this getting into shape for 1.4 and can contribute OS templates but still need developer's help with Foreman's inner workings.
