Network boot live ISO

January 29th, 2014 by

The x86_64 edition of openSUSE Education’s Li-f-e live DVD supports PXE booting the iso over the network, here is how to do it:

* Install Li-f-e on a server from which other machines will PXE boot, make sure you have plenty of space assigned to / partition(about 20G)
* Set up LTSP by following this quick start guide
* Create /srv/nfs folder and copy Li-f-e iso there
* Run the following as root in terminal:

mount /srv/nfs/openSUSE-Edu-li-f-e.x86_64-42.1.1.iso /mnt
cp /mnt/boot/x86_64/loader/linux /srv/tftpboot/boot/linux-life64
cp /mnt/boot/x86_64/loader/initrd /srv/tftpboot/boot/initrd-life64
echo "/srv/nfs *(ro,no_root_squash,async,no_subtree_check)" >> /etc/exports
cat <<EOF>> /srv/tftpboot/pxelinux.cfg/default
LABEL Li-f-e
kernel boot/linux-life64
append initrd=boot/initrd-life64 isofrom_device=nfs:10.0.0.254:/srv/nfs/ isofrom_system=/openSUSE-Edu-li-f-e.x86_64-42.1.1.iso
IPAPPEND 2
EOF
chkconfig rpcbind on && service rpcbind restart
chkconfig nfsserver on && service nfsserver restart

Now you can PXE boot any machine over the network, select Li-f-e from the end of the boot menu to boot live DVD iso instead of normal LTSP session.

Use “yast2 live-installer” to install Li-f-e on the client machine.

Merging SVN Repositories Explained

October 30th, 2010 by

Adding files to a SVN server is usually a task done in seconds. However, having several independent SVN repositories and wanting to “combine” them, this is not trivial—especially if you want to preserve the history.

The doc team had had three different, independent repositories on BerliOS (opensuse-ha-doc, opensuse-docmaker, and opensuse-lfl) all holding separate information. This was a bit silly, so my task was to consolidate them into opensuse-doc by keeping all history.
