The ubuntu, and ubuntu-minimal elements both make use of a common set of environment settings to determine the distribution name. The ubuntu-minimal element also does a few extra things which would appear to apply to both sets and bring in extra architecture support. As such, these are included in the common element. This intends to be part of a series of patches which will eventually create a new element to build a minimal ubuntu-systemd-container element which can be used for lxc/nspawn containers.

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+.
