I know this is not strictly a cobbler question.....

I use cobbler to install FC21. I end up with a grub file with init16 and linux16 in it. The system will boot if the BIOS is set to boot from the disk, but it hangs if I let it PXE boot and then chainload (is that the right word) to the local disk. 

Also, it will work with PXE if I change initrd16 to initrd and linux16 to linux 

Any suggestions? Right now I am simply munging the grub config file in my kickstart script.
