I have been using a ACER AspireONE D257-13685 netbook running CentOS 6.6 as my
portable kickstart server for more than a year successfully. This is because I
work in different datacenters and a highly portable kickstart setup is very
desirable.
I have the following in the /etc/yum.repos.d:
[root@kicker yum.repos.d]# lsCentOS-Base.repo CentOS-fasttrack.repo
CentOS-Vault.repo epel-testing.repo mirrors-rpmforge
mirrors-rpmforge-testingCentOS-Debuginfo.repo CentOS-Media.repo epel.repo
home:libertas-ict:cobbler26.repo mirrors-rpmforge-extras rpmforge.repo
So, whenever there is a new cobbler release, the netbook will have it.
Earlier today, I did yum update on the netbook. After that I did a couple test
kickstart and soon observed failures. As usual I did the cobbler system getks
--name=... as a first check to see if the kickstart is rendered or not.
Immediately I got:
[root@kicker ~]# cobbler system getks --name=sc2u0n0
# This kickstart had errors that prevented it from being rendered correctly.
# The cobbler.log should have information relating to this failure.No. The
/var/log/cobbler/cobbler.log isn't helpful at all. So, with divide and conquer,
by commenting out different sections in the kickstart template, I soon
concluded that the pre_install_network_config is the culprit.
I even copied over the latest pre_install_network_config from the project's
github master. Then put it in /var/lib/cobbler/snippets. No go.
Luckily, I have another cobbler server for my office LAN, which retrieves
cobbler from epel, so it's still on 2.6.3. Copying over its
pre_install_network_config, then cobbler system getks --name all worked again.
I then tried to review the difference between the two,
pre_install_network_config.org is the one that came with 2.6.8. But I couldn't
see why the one that came with 2.6.8 would fail the Cheetah parser.
Would appreciate any hints.
