| Note that this setup still requires the scripts provided on this page, the creation of /etc/fstab, and the creation of /boot/grub/menu.lst. Some users may have difficulty using Gnome unless they add '' iface lo inet loopback'' and ''auto lo'' to /etc/network/interfaces. Always make certain to run ''update-initramfs -c -k all -v'' after any changes to keep your system booting happily. When you are finished creating/customizing /etc/fstab, /boot/grub/menu.lst and /etc/network/interfaces you will have a basic bootable image suitable for reuse. Setting up a new client is as simple as: copy the image, use vblade to make the new image available, mount the image, edit the specifics (ie: /boot/grub/menu.lst, /etc/hosts, etc) then boot from your new client. Once you have booted this basic image, making it a full system is as simple as apt-get install ubuntu-desktop, ubuntu-server, xubuntu-desktop, kubuntu-desktop, or whichever you choose. | Note that this setup still requires the scripts provided on this page, the creation of /etc/fstab, and the creation of /boot/grub/menu.lst.

| + | For debugging issues related to a boot device not being found, | ||
| + | ''debug=mount'' is probably most useful. | ||
| + | |||
| + | See ''initramfs-tools(8)'' for further details. | ||
| + | |||
| + | Things to look out for include: | ||
| + | |||
| + | * Has the driver for the NIC been loaded? | ||
| + | * Is the interface "up"? | ||
| + | * Has the ''aoe'' kernel module ben loaded? | ||
| + | * Does ''/dev/aoe/'' exist, does it contain the necessary entries? | ||
