Hi
I've seen that Koan puts kickstart inside the initrd.img and
references it as file:ks.cfg, but I don't know the reason for this.
The reason for this is that when Anaconda restarts the NICs for the
first time after
BIOS, there is a rather short DHCP timeout, and depending on network
issues (such
as portfast config), the system may not consistantly achieve DHCP before
timeout.
This workaround allows for --replace-self to /always/ work because
network connectivity
is not needed to retrieve the kickstart.
See http://fedoraproject.org/wiki/Anaconda/NetworkIssues
In order to enable auto-registration (based on
pxelinux.cfg/defaults entries), the ks should we changed by this diff on
koan/app.py:
It is true that this will bypass auto-registration, but this will only
affect reinstalls, which do not update the regisration information
anyway. My main concern for auto-registration is initial machine
provisioning and new virt machines, so I suspect this is not a huge
limitation.
We could /possibly/ add a helper flag for --replace-self called
"--embed-kickstart" and make the default to not do that, though as many
times as it comes up, I believe the kickstart embedding is useful.
Now, folks might ask "why not just do registration via a wget" in %pre,
but that's apparently not valid because mac address information is not
passed along in %pre scripts -- and we do want that data.

So the ks= would be constructed with the cobbler-provided ks
