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+.
