Minimal snapshots for cooker available.

Hi,

Since it's currently pretty painful to install cooker from scratch (at
least for me since I'm upgrading a 2011 distro, updating more than 1200
packages), I'm going to make available a couple of snapshots of cooker.

The snapshot is basically a raw disk image with 3 partitions: swap,
/boot (ext3) and / (btrfs).

It contains a minimal set of packages to get a reasonable image size
(currently 163MB, xz compressed). So don't expect to find KDE already
installed but at least it still can be used to test some low level
stuff.

The initrd should be generic enough to boot any HWs, please see below
for details.

Here are some use cases:

  - with qemu:  "qemu-kvm -hda <image>"

  - with virtualbox: convert the raw image into the 'vdi' format by
    virtualbox:

      VBoxManage convertfromraw <image>.img <image>.vdi

    and you're ready to run cooker through virtual-box.

  - with real HW: you can dump the image into a real disk and boot from
    it. For example if you want to boot cooker from a USB stick, just
    plug it and initialize it with something like:

      $ dd if=<image>.img of=/dev/sdX bs=8096

    where sdX is the device node associated to your USB stick. Then
    reboot and if your bios is configured to boot USB devices first that
    should work.

The snapshots can be found at:

I'll try to release a snapshot every month.

Cheers,
