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. Change-Id: I8ce65e1d357d15e8ed8995ad1dcaea02bbd1986f

|
|
|
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+.
