I have been testing the latest cobbler for PXE booting Ubuntu 12.04.1-server-x86_64 and 12.10-server-x86_64 using a Scentific Linux 6.3 host to run the cobbler server. With the former, I got everything going. But with the later, I haven't been successful.

As an attempt to figure things out, I downloaded Ubuntu's cobbler 2.2.2 source package. Examining the content, I soon noticed that Ubuntu's cobbler 2.2.2 came with a cobbler-ubuntu-import bash script. I reviewed the code and spotted something interesting: line 9 of the script states:

9 AUTO_KOPTS='log_host=@@server@@ log_port=514 priority=critical locale=en_US netcfg/choose_interface=auto'

But after extensive googling, reading both Debian and Ubuntu's documentation about the debian-installer, I don't see these two kopts log_host and log_port documented anywhere.

Putting it in the profile of my current test setup, even my cobbler server host does run rsyslogd, I don't see anything logged either. No, I don't have iptables and selinux on on the cobbler server host.

Can anyone point to me where I can read more about these two options? Having the ability to log an installation to a remote central logging host would be really cool.
