Hi David, thanks a lot for your support :-)
The latest beta packages are versionned with 4.3.0-0.16. This releases now
builds with perl files installed in INSTALDIRS=vendor (no more use lib
/usr/lib/systemimager needed).
This version includes the si_monitortk thread warning fix.
It is available here: http://svn.oscar.openclustergroup.org/repos/unstable/
The package has been built for rhel-6, debian-6, fedora-17
For the future, as I said, I'm looking forward for any info/doc/script on how
to build such a thing:
http://ftp.free.fr/mirrors/fedora.redhat.com/fedora/linux/releases/20/Fedora/x86_64/os/images/pxeboot/initrd.img
Best regards,
Olivier.

Subject: [sisuite-users] RE : support newer kernels in systemimager?
Hi,
Sorry for not participating often here, I'm extremely buzy working on releasing
a new stable OSCAR cluster release that will support many distros.
Though, I'm still working on SystemImager. (just fixed si_monitortk thread
warning)
The current git should support kernels from 2.4 to 3.99 if it ever exists.
We have built beta release here:
http://svn.oscar.openclustergroup.org/repos/unstable/
For more info, here is my analysis of the current situation and what I'd like
to achieve:
Problem of the current release is that it fails to build template initrd and
kernel on newer distros (like fedora-18+). The problem is that template initrd
is based on udev when newer kernels needs latest udev version and build
mechanism is not yet designed to build udev without systemd from systemd source
tree.
IMHO, the way to generate templates is not compatible anymore with the variety
of distros and kernel version. rhel6 is using a 2.6, while other distros are
using kernel 3.x
Building latest kernel and lvm on an old system (rhel6) using installed system
kernel includes leads to build failures or runtime crash.
2 solutions for the future:
1/ have different build tree for each distro with apropriate kernel => means
old distro won't be supported on recent hardware . typically, our vanilla
kernel-2.6 supports far less hardware that patched rhel-6 shipped kernel. =>
bad idea and very difficult to maintain.
2/ drop the idea to build our kernel and initrd from scratch and instead build
the initrd using dracut. Big benefits:
a/ we support the same hardware as the linux vendor. even with old kernel.
b/ building the rpm is far more faster
c/ far more stable. no more lvm built for kernel 3.10 using kernel 2.6 build
host system includes.
UYOK would still be possible for users having hardware that is not supported by
their linux vendor, but for the majority of cases, the templates would be far
sufficient.
Unfortunately, I'm still searching a doc that tells how to build a non basic
initrd.
Our case is similar to
http://ftp.free.fr/mirrors/fedora.redhat.com/fedora/linux/releases/20/Fedora/x86_64/os/images/pxeboot/initrd.img
=> If someone can point me to a page that explains how this image is built,
that would be AWESOME.
It uses systemd and udev for loading hardware drivers and minimal services like
network and so. Basicaly it havs everything we need.
Then we would just have to add needed binaries (lvm tools, ...) from installed
system and (build)our specific stuffs like flamethrower client or bittorent
client and replace stage2 loader with our rcS and voila! (cleaner, faster,
higher ...;- )
Best regards.

https://wiki.ubuntu.com/Kernel/LTSEnablementStack
The patch will fix your problem running si_prepareclient (though I can image
that I could not do the network boot on that kernel (still using an old 2.X
Ubuntu 11.04 kernel).
My images are also converted to grub1 instead of grub2, and the master script
edited to have ext3 not ext4, and a similar patch to allow the server to upload
from an ext4 golden client.
I'm looking forward to a new release of SI for Ubuntu 12.04 and 14.04 support!

Jan

ERROR: unsupported kernel 3.5.0-23-generic!
The warnings or errors about "Use of uninitialized value $v1 in split at
/usr/lib/systemimager/perl/SystemImager/Common.pm line 199" is due to
the way parted is now returning multiple line of text output when the
--version option is passed. It seems that the perl code that is supposed
to be parsing the stuff that is not able to handle that multi-line
output to extract the version of the parted utility.
However what concerns me most is the message back that says the
3.5.0-23-generic kernel is not supported.
Is there any documentation available for systemimager that would show
the necessary process steps to incorperate support for newer kernels?
Any suggestions about any of this would be most appreciated. BTW, I have
the following installed on the Ubuntu system:
ii systemconfigurator 2.2.11-1 Unified
Configuration API for Linux Installation
ii systemimager-client 4.1.6 Utilities for
creating an image and upgrading client machines
ii systemimager-common 4.1.6 Utilities and
libraries common to both the server and client
ii systemimager-initrd-template-amd64 4.1.6
SystemImager initrd template for amd64 client nodes
