When installing Sat 5.3, the installer never prompts for a certificate and always uses the one in /usr/share/spacewalk/setup/spacewalk-public.cert. This one should not be shipped at all.
Fixed in svn revision 177292. Removed the spacewalk-public.cert and the reference to it in defaults.conf.
On Satellite 530-re20081223.2, no cert found and installer prompts for information not contained within defaults.conf. Moving to VERIFIED.
Clarification: installer does not actually load in defaults.conf by default anymore... all prompts arose from not having a configuration file loaded. My B, dawg.
