[systemd-devel] mkosi config to build minimal Ubuntu 22.04 VM image?

[Daan De Meyer]

Hi Paul,

Ubuntu 22.04 is too old to run mkosi on. Your best bet is to use the
tools tree functionality. By adding ToolsTree=default and
ToolsTreeDistribution=debian, mkosi will build a debian image and use
that image to do the final build. That will help you get around the
lack of bootctl on Ubuntu Jammy. Do note that mkosi is a fast moving
project and you might be better off running a distribution such as
Fedora or Arch Linux which will generally have more up to date tooling
than the latest Ubuntu LTS release.

Cheers,

Daan
