Michael Johnson e433aebf7d Add DIB_UBUNTU_KERNEL to ubuntu-minimal
This patch adds a new environment variable to the ubuntu-minimal
element called DIB_UBUNTU_KERNEL that allows you to specify the kernel
meta package that will be using to install the kernel inside the image.
It supports "linux-image-generic" (The default), "linux-image-kvm", and
"linux-image-virtual".
This allows building images that are smaller in size (~200MB smaller
qcow2) that have only the kernel modules necessary for virtual
machines.

ubuntu-minimal

The ubuntu-minimal element uses debootstrap for generating a minimal image. In contrast the ubuntu element uses the cloud-image as the initial base.

By default this element creates the latest LTS release. The exact setting can be found in the element's environment.d directory in the variable DIB_RELEASE. If a different release of Ubuntu should be created, the variable DIB_RELEASE can be set appropriately.

Note that this element installs systemd-sysv as the init system for 18.04+.

Environment Variables

DIB_UBUNTU_KERNEL:
Required

No

Default

linux-image-generic

Description

Specifies the kernel meta package to install in the image.

Example

DIB_UBUNTU_KERNEL=linux-image-kvm

Options

linux-image-generic, linux-image-kvm, linux-image-virtual

Notes

The element must know about the package, otherwise it will select the default.
