We have a DHCP/PXE server in a build environment, which is separate from our Spacewalk v1.5 server. We direct builds to Satellite or Spacewalk based as needed. It contains initrd & vmlinuz files for each version/arch we currently deploy for both RHEL & CEL. I'd like to keep the storage footprint to a minimum, if possible. Keeping a big directory of ISOs to loop-mount for kickstart profile distributions seems excessive, especially when DVD#1 exceeds 4GB now. Is there any way around this requirement for kickstarting?
