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.

ubuntu-systemd-container
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+.
