Canonical employees have revealed information about the ubuntu-mini-iso project, which develops a new minimalistic build of Ubuntu, about 140 MB in size. The main idea of ββthe new install image is to make it universal and represent the ability to install the selected version of any official Ubuntu build.
The project is being developed by Dan Bungert, maintainer of the Subiquity installer. At this stage, a working prototype of the build has already been prepared and tested, work is underway to use the official Ubuntu infrastructure for building. The new build is expected to be published with the spring release of Ubuntu 23.04. The assembly can be used for burning to CD / USB or for dynamic loading via UEFI HTTP. The assembly provides a text menu with which you can select the edition of Ubuntu of interest, the installation image for which will be loaded into RAM. Data about available assemblies will be loaded dynamically using simplestreams.
