Research direction

No files or tests are named. Start by breaking the proposal into its listed areas: systemd units, Ubuntu package delivery, /var/cache use, network-stack ownership, kernel support, and testing. Done would require evidence that ZOS services can operate on Ubuntu across all of these areas.

Written by the indexing model from the issue text.

Description

type_feature

ZOS normally include a kernel, base image plus full zos services that takes care of the entire operation. The idea what have a tiny as compact as possible no install linux system that works simply by booting the kernel image.

This also means since the operation of ZOS is provided by normal services and daemon and many simple tools that we still can run these service on any linux system (say ubuntu) with some major changes (not ordered)

  • Services then need to have systemd unit files for auto-starting instead of the zos zinit process manger
  • Shipping the binaries via system packages, this way updates (and automated updates) are distributed via the apt system
  • No cache, since system already is installed zos will need to just use the current system installation directory /var/cache while this should work out of the box it need to be well tested
  • ZOS need to take over the entire network stack means uninstalling NetworkManager and/or systemd network daemons.
  • Verify that the default ubuntu kernel contains already all what we need
  • Lots and lots of testing
