Re: [cobbler] Server still has DHCP address after being built with Ubuntu 14.04
Hi Russel,
Thanks for this information. I did managed to resolve my issue in a similar
fashion based on this cobbler list post
<https://lists.fedorahosted.org/pipermail/cobbler/2014-May/009388.html>;.
The following appears to work even though it didn't on my first attempt,
but I added the trailing semicolon and it worked, but I may have done
something else along the way:
d-i preseed/late_command string wget -O-
http://$http_server/cblr/svc/op/script/$what/$name/?script=preseed_late_default
| chroot /target /bin/sh -s; cp /target/etc/network/interfaces
/etc/network/interfaces;
I've never dug into the cobbler package sources (wasn't even familiar with
them), but I've now looked at the finish-install udeb package and it's very
enlightening. I have a lot more to learn now. Is there anywhere that more
fully documents all of the debian-installer "modules" (i.e. pkgsel, netcfg,
etc.), besides this <https://help.ubuntu.com/community/Cobbler/Preseed> and
this <https://help.ubuntu.com/12.04/installation-guide/example-preseed.txt>?
It all still seems very cryptic at times and I'm really trying to better
understand and improve my cobbler build server (seed files, cheetah
templating, the entire detailed cobbler kickstart process from start to
finish, etc.)
Thanks,
Justin

After the seed file execution is complete (and beyond even preseed
_late_default) /etc/network/interfaces is being overwritten by the
finish-install process. That means that the custom /e/n/i file generated
and put in place by post_install_network_config_deb is simply wiped out. You're
supposed to be able to short-circuit finish-install by some seed setting
... but, for reasons unknown, it doesn't work. (I believe this is related:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=698626).
Anywho ... the workaround that I came up with was to remove a couple of
scripts executed by the finish-install process that were doing the
overwriting:
d-i preseed/late_command string rm -f
> /usr/lib/finish-install.d/55netcfg-copy-config
> /usr/lib/finish-install.d/50config-target-network; wget -O-
http://$http_server/cblr/svc/op/script/$what/$name/?script=preseed_late_default
> | chroot /target /bin/sh -s
If you look at the package source for finish-install you'll be able to
confirm for yourself that those particular files are responsible for the
overwrite.
