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+.
