As noted inline, this works around potential issues by being a strong indication you are in a container (e.g. [1]). Since nothing should be changing anything on the host/build system, this is a generically safer way to operate.

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+.
