Installation Repo Vs. Software Repo?

view full story

http://forums.opensuse.org – I'm trying to set up a PXE Boot Installer for Linux. The problem I'm having right now is that our standard repo that was have set up (http://MYHOST/repo/$RCE/SLES11-Online/sles-11-x86_64/) doesn't seem to be working as an install point (I keep getting "no repository found"), even though it works great as a means for a software repo (Its used by several hundred other servers) Is there a difference between a software repository and an installation repository? Thanks in advance! (Distributions)
