A new breed is needed to not let cobbler insert additional kernel options in pxegen.py
(line 460) that are not needed and only add confusion.
Options that I see being added, but are not usefull for livecd's:
- Kssendmac
- Syslog
- Ks (or Auto and Url for debian)
- Lang
- Text
- Ksdevice
The same is for the debian breed, also the RedHat specific ksdevice, kssendmac and syslog
options are added.
Sure, I was trying to avoid making a concept of a "live" breed, when the
live handling as documented (livecd-iso-to-pxeboot) largely works for
Fedora-based live CD's only (which includes the Dell Firmware updates).
I think a breed called "generic" would be fine. Import would not work
for generic and it would be very much a "set it up on your own" sort of
thing.
