ubuntu-minimal

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+.
