Included a script to enable generating systemd-sysexts. Successfully
tested sysext generation with a fresh Flatcar image (e.g., Python and
Neofetch system extension). Part of my internship work.
The current OS images we provide are not OK as base for flatcar specific
sysext images: it lacks the package metadata and portage configuration,
in order to keep end user OS image clean. This script retains this
information and allows you to produce systemd-sysexts to extend the
system. This script can be used to build a Flatcar sysext image.
Recommended to run from image build folder.
