In order to allow the simple preparation of base images which can be used for LXC/nspawn machine containers, we add this element. Containers inherit a kernel from the host, so there is no need to build a kernel into the image. All the element needs is a base init system which, in this case, is systemd.

|
========================
|
|
|
|
The ``ubuntu-systemd-container`` element uses debootstrap for generating
|
|
a minimal image for use by machine containers. In contrast the ``ubuntu``
|
|
element uses the cloud-image as the initial base and the ``ubuntu-minimal``
|
|
builds an image to be used for hosts.
|
|
|
|
By default this element creates the latest LTS release. The exact
|
|
setting can be found in the ``ubuntu-common`` 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+.
