The boot environment for non-cloud disk images was incomplete,
leading to images not bootable on real hardware. This change
adds the missing packages to fix that.
The bootable image support for ELN differs from boot.xml in
several ways:
* The images use XFS
* Several packages are dropped that are not present in ELN
