Your download should begin in a few moments. If you have trouble downloading the file, please try this link.
After you've downloaded and extracted starcluster-base-ubuntu-9.04-x86_64.iso.gz, run the following commands to login to the iso image:
$ sudo -i
(enter root password)
$ mkdir -p /mnt/starcluster-base-ubuntu-9.04-x86_64
$ mount -o loop /path/to/starcluster-base-ubuntu-9.04-x86_64.iso /mnt/starcluster-base-ubuntu-9.04-x86_64
$ mount -t proc none /mnt/starcluster-base-ubuntu-9.04-x86_64/proc
$ mount -o bind /dev /mnt/starcluster-base-ubuntu-9.04-x86_64/dev
$ cp -L /etc/resolv.conf /mnt/starcluster-base-ubuntu-9.04-x86_64/etc/resolv.conf
$ grep -v rootfs /proc/mounts > /mnt/starcluster-base-ubuntu-9.04-x86_64/etc/mtab
$ chroot /mnt/starcluster-base-ubuntu-9.04-x86_64 /bin/bash
If you'd rather not have to run these commands by hand (or remember them for that matter), you can download a simple script to do this for you (only tested on Linux). To use this:
$ sudo -i
(enter root password)
$ mkdir -p /mnt/starcluster-base-ubutu-9.04-x86_64
$ python /path/to/chroot_iso.py /path/to/starcluster-base-ubuntu-9.04-x86_64.iso /mnt/starcluster-base-ubuntu-9.04-x86_64
