1. Take the root image from a pristine SLES 10.2 repository, and copy

cp -avr $WORKING_DIR/mnt/* $WORKING_DIR/rootimg
umount $WORKING_DIR/mnt

2. Replace the original ‘yast’ script with my own script.

mv $WORKING_DIR/rootimg/sbin/yast $WORKING_DIR/rootimg/sbin/yast.real

The Kusu installer is made up of 2 parts: the screens (context-specific info and prompts), and the navigation framework. In this document, I will describe the screens. ...

Liming and I took delivery for some shiny new hardware at our data centre today. These are a Dell 1950, and 2950 with dual Quad-core Xeon CPUs and 8GB of RAM each. The 1950 has two 15k, 300G SAS drives, while the 2950 has three 10k, 400G SAS drives. Very nice!



The 2950: Don’t carry this alone!

Greetings true believers!

I’m George Goh, one of your friendly neighbourhood cluster monkeys. Najib, our lead ape, has granted me access to blog here about general things happening in the OSGDC, and more specifically, Project Kusu and the components that I maintain, so let’s get things rolling… .
