Hmm, yes, I need to move that page back to "Developer Docs" and add some clarifications.

Another problem is the live CD sometimes didn't detect certain storage controllers that the normal installer environment would detect. https://bugzilla.redhat.com/show_bug.cgi?id=457488 > Would the livecd work with F8 and older livecd files from git or have there > been other changes to cobbler which would prevent the livecd from working? > Shouldn't be, though I'd say F10 should work equally well. FWIW, there's only 3 different things different when we invoke koan from the live CD: if self.live_cd: cmd.append("--bad-image-okay") cmd.append("--boot-filesystem=/dev/sda1") cmd.append("--config-file=/tmp/boot/boot/grub/grub.conf") It's the --bad-image-okay flag that is broken... (For you, a cleaner route might be to just use "cobbler buildiso" and then convert the ISO into a USB image, to save from burning some discs. Things still remain somewhat static but they save from wasting CD's... also note that new images are only required when adding new profiles or system entries ... the kickstarts themselves are generated remotely from the cobbler server) > Thanks, > > Tim > > -----Original Message----- > From: [email protected] > [mailto:[email protected]] On Behalf Of Michael DeHaan > Sent: Monday, January 12, 2009 6:48 AM > To: cobbler mailing list > Subject: Re: Cobbler LiveCD question > > Flink, Timothy wrote: > >> I'm new to cobbler and I am trying to get the LiveCD working as I am not >> able to change the dhcp server.
