Restoring an inherited value for a child profile?
by Zack Perry
I have a profile that is created using the command:
cobbler profile add --name=... --parent=...
The child profile's 'Template Files' attribute originally inherited
from its parent. For testing, I changed it using
cobbler profile edit --name=...
Once I was done, I thought that the defaults in the parent profile
were sufficient, so I wanted to restore the <<inherit>> value. But,
neither cobbler profile edit --help nor man cobbler offer any hints
how to do so. I tried the cobbler web UI as a last resort, no dice
either.
Yeah, I can cobbler profile remove --name=... to delete the modified
child profile and then recreate it. It's not that hard, but
conceptually it's uneconomical :-(
So the Q: is it possible to restore an inherited value for a profile
attribute? If so, what is the correct work flow?
Regards,
--Zack

Re: [cobbler] cobbler 2.4.0 and problems booting Ubuntu 12.10 desktop 64bit
by Zack Perry
Hi James and Andrew,
Thanks for your two's follow-up. Looks like it's probably a good idea to file a bug report upstream to Ubuntu to Debian's Installation Team? Personally, I think what Ubuntu has done qualifies as a "bug".

Gentlemen, please give me a few days. I still have a couple of ideas
to try out before we give up on Ubuntu 12.10 and later completely. I
have a couple of other ideas to try out. Will report back to the list.

Project Status and Direction
by James Cammarata
Hey all, just wanted to send out a quick update on the project status.
The release24 branch has been receiving patches, and is alpha quality.
I'm looking for more users to check it out and give it a test. One of
the biggest holdups to this release is the documentation. The 2.2.3
manual will need to be forked and updated with all of the new features
in 2.4.0, such as:
* Dynamic settings - no more needing to restart cobblerd when changing settings.
* Better debian/ubuntu support (better preseed, more snippet support, etc.)
* Support for bonded bridge interfaces (useful for virtual hosts)
* OpenVZ support as a virtualization type
* Web GUI improvements
* Alpha support for MySQL as an alternate storage backend
And probably a few more that I'm forgetting. So, if you're familiar
with any of these features, take a look at the docs repo - any help
updating the docs would be appreciated. Right now, a lot of the pages
content was essentially just copied from the wiki, so there is a lot
of cleanup left to do. Once the manual is forked, we're going to have
to do that in two places, so it'll be easier to tackle now before we
fork it.
There are two primary goals on my road map right now:
1. Work towards adding support for IaaS platforms like OpenStack,
Eucalyptus, etc.
2. Improve unit testing and continuous integration testing with Jenkins.
Both of these goals require some dedicated hardware, so to help fund
those goals I have created an Indiegogo campaign:
http://www.indiegogo.com/cobbler24
This will be the only time I mention this on the mailing list, but I
will put it up on the project home page and mention it via twitter. So
any help in getting the word out will of course be greatly
appreciated.
Overall, I think the project has been moving in a positive direction,
and the last 6 months have flown by since taking over as maintainer.
Any comments or other feedback are always welcome. Thanks!

While we are on the subject of netboot issue, I also spotted something
odd. AFAIK, the ubuntu-12.10-desktop-amd64.iso and
ubuntu-12.10-server-amd64.iso do not provide working netboot images
for PXE network install. Please see my test report in this regard:
http://www.mail-archive.com/cobbler@lists.fedorahosted.org/msg08210.html
As a result of my digging around, I found
lubuntu-12.10-alternate-amd64.iso (never tried it before). But the
iso IMHO has a funny aspect to it. Lets take a look of the
above iso's content, loop mounted on /mnt:

Note that the Packages.gz in universe/debian-installer/binary-amd64
has no content, but its counterpart in universe/binary-amd64 does.
I have tried to use the iso burned to a CD to do an install. The
Lubunbun desktop did get installed, even without an Internet
connection (I pulled the wire ;-)
But up to now, if I try to do a PXE network install, the only way
that I can get a desktop installed is to add a locally mirrored
repository with a d-i apt-setup/local0/repository ... preseed
debconf-set-selections command.
I even tried to replace the Packages.gz in
universe/debian-installer/binary-amd64
with the result of dpkg-scanpackages, gzipped, but the graphical
login is still missing after the install.

RFC: adding a cobbler debmirror.template?
by Zack Perry
As of now, cobbler has the following etc templates <https://github.com/cobbler/cobbler/tree/master/templates/etc>:
dhcp.template dnsmasq.template named.template rsync.template secondary.template tftpd.template zone.template
For those of you who need to deal with Debian/Ubuntu network install,
what do you think about adding a debmirror.template to the collection?
Rationales: the use of debmirror is no less complex than say dnsmasq,
rsync, and definitely more so than tftpd. These three have templates,
so why debmirror can't?
Motivation: recently Canoncial decided to stop providing a full
alternate iso for its default release. There are alternate install
isos for other variants, but IMHO the digging and reviewing a
collection of disjointed documentation (often are out of date or
somewhat inaccurate) is such a waste of time. One of cobbler's main
design goal is to mask the complexities of serveral tools typically
used for PXE network install. Given what Ubuntu has done, IMHO
debmirror becomes an important tool and thus qualifies to have
a template.

Cobbler uses DHCP instead of a static IP
by Paul.Goessinger＠dab.com
Hi,
We are using cobber to manage our machines for our satellite. Re are using satellite 5.5 with cobbler 2.0.7. Since our last upgrade, our VMWare Machines do not use the static IP anymore during kickstart.
NOTICE NetworkManager: ifcfg-rh: Ignoring connection 'System eth0' and its device due to NM_CONTROLLED/BRIDGE/VLAN.
Before the upgrade, this worked.
We use this cobbler command to add the machine:
cobbler system add --name=thename --profile=theprofilename --hostname=thename --kopts="ksdevice=eth0 umgebung=LAN" --interface=eth0 --static=true --mac=00:50:56:9b:2e:c6 --ip=6.7.8.9 --subnet=255.255.255.0 --gateway=3.4.5.6 --name-servers=1.2.3.4
What are we doing wrong? I searched for different combinations of cobbler, NetworkManager, DHCP etc. but I did not find any usable answer. I hope this is a cobbler problem.
Cheers,
Paul

cobbler 2.4.0 Ubuntu repository mirroring hostname off-by-one parsing error?
by Zack Perry
cobbler: 2.4.0 from epel-testing
host : SL 6.43 64 bit
In http://cobbler.github.com/manuals/2.2.3/4/7_-_Package_Management_and_Mirr... "Also apt" section, there is this example:
cobbler repo add --name=foo --mirror=http://url --breed=apt --arch=i386
So far, I have been using either ISO image import or apt-mirror to do direct Ubuntu mirror as debmirror was not available for RHEL for quite some time. But now since debmirror is on my cobbler server, so I decided to give cobbler's apt mirror a work-out:
[root@cobbler ~]# cobbler repo add --name=ubtest --mirror=http://us.archive.ubuntu.com --breed=apt --arch=x86_64

So, the character 'm' in the us.archive.ubuntu.com got chopped off before the source hostname was fed to debmirror. Looks like there is an off-by-one error in action_reposync.py?

How to enable a graphical install for RHEL desktops?
by Zack Perry
cobbler: 2.4.0 from epel-testing
server : SL 6.3 64 bit
Today I attempted to PXE boot the desktop of Fedora 17. According to
the Fedora 17 kickstart documentation, the graphical mode should be the
default, but the first time, the installer ran in text mode. After the
installation was done, I was greeted by just a text console with the
login prompt :-(
So, I modified the kickstart template such that for desktop
installation, it used the 'graphical' option. This worked. Fedora 17
installer ran in graphical mode. The firstboot program launched, and
the desktop UI came up.
Next, I tried Scientific Linux 6.3 desktop. This time, the same symptom, but using the 'graphical' kickstart option didn't help.
Feeling curious, I did the following:
[root@cobbler ~]# cobbler system dumpvars --name=nb1|grep text
kernel_options : ksdevice=bootif lang= graphical keyboard-configuration/layoutcode=us interface=eth0 text locale=en_US kssendmac priority=critical
BTW, the 'graphical' shown in the above line was added by me just for
testing.
I knew that I didn't set the 'text' kernel option (doubled checked the profile and system objects just to make sure), so I checked the
source, indeed:
In cobbler/settings.py, there is the following:
78 "kernel_options" : [{"lang":" ", "text":None, "ksdevice":"eth0"},"dict"],
Also, in /etc/cobbler/settings, there is the following:
[...]
# kernel options that should be present in every cobbler installation.
# kernel options can also be applied at the distro/profile/system
# level.
kernel_options:
ksdevice: bootif
lang: ' '
text: ~
[...]
Now, I understand that very few people would use RHEL as desktops. Fedora? Sure. But setting the installation always to text mode seems
to contradict with the official RHEL 6 Installation Guide.
Is there a way to get the documented behavior, i.e. graphical
by default, use text mode when desired?
