Unable to netboot with dhcpd managed by cobbler

[James Page]

cobbler manages the isc-dhcp-server instance that run alongside it in my test deployment; prior to upgrade to oneiric it was able to manage /etc/dhcp/dhpcd.conf fine - however now when cobbler generates this file using 'cobbler sync' I always get a gpxe filename rather than pxelinux.0:

# group for Cobbler DHCP tag: default
group {
    host mercury.shouse.local {
        hardware ethernet <HIDDEN>;
        fixed-address <HIDDEN>;
        option host-name "<HIDDEN>";
        filename "gpxe/menu.gpxe";
        next-server <HIDDEN>;
    }
}

use_gpxe is set to 0 in /etc/cobbler/settings so this is a little inexpected.

Workaround: fix filename to "pxelinux.0" in /etc/cobbler/dhcp.template

Status changed to 'Confirmed' because the bug affects multiple users.

I can confirm that the pxelinux.cfg files for hosts generated using cobbler version 2.1.0+git20110602-0ubuntu26 generate gpxe/menu.gpxe configurations no matter what the setting in use_gpxe.

Unfortunately fixing "filename '/pxelinux.0'" has no effect when booting hosts. They're still trying to boot gpxe/menu.gpxe

[David Dyball (david-dyball)]

Scratch that... I was changing the filename option under the subnet, not under the host template. Changing that works. Looking forward to a fix.

cobbler (2.2.2-0ubuntu7) precise; urgency=low

  * debian/patches:
    - 45_add_gpxe_support.patch: Updated to only use menu.gpxe when gpxe
      is enabled and not always. (LP: #8417268)
    - 61_ubuntu_pxe_chainc32_default.patch: Use chain.c32 for localboot,
      rather than 'LOCALBOOT -1' by default. (LP: #898838)
