Public bug reported: Previously, WSL instances relied on a very lightweight build pipeline which was using the CPC image. In 22.04 we did a first step to have WSL has its own project in livecd-rootfs, with its own seed and image to produce a rootfs.
However, a lot of ubuntu differentatior (enabling systemd by default, managing upgrade policy based on the distribution name, cloud-init enablement) were relying on an .exe file, ran on first launch, to ensure that those policies were modified. Microsoft is going to remove soon those launcher, and so, we won’t have an entrypoint to modify those policies. We thus needs to ship between one and three rootfs, varying on the upgrade policy (we produce multiple Windows applications on the store). This work has started on 24.04, and rely on cloud-init, (shipping pro client too for future wsl pro service offering). We thus needs to align our previous LTS on the latest state of art for WSL. Note that 20.04 will be more involved and will be treated separately. This is about aligning 22.04 and 24.04. What is needed in 22.04: - ensure livecd-rootfs can create between one and 3 tarballs, with different upgrade policy and enable systemd by default as a non conffiles. - ensure we ship the same set of default application (aligning the seed), to include cloud-init and other tools that developers expect on a WSL system. Also, the pro client is shipped as it will be required with our new Pro on WSL offering. - ship wsl-setup: * it will drop some systemd experimation (that was never enabled by default), * it’s moving all the systemd units adjustements to take into account a WSL environment (Microsoft kernel, being a distro inside its own namespace running in parallel to other distros…) * enable cloud init WSL datasource * remove core 22.04 support and installer wrapper script as we don’t ship snaps by default anymore nor installer. * report the status of cloud-init in MoTD if it fails What is needed in 24.04: - ship wsl-setup: * it’s moving all the systemd units adjustements to take into account a WSL environment (Microsoft kernel, being a distro inside its own namespace running in parallel to other distros…) * enable cloud init WSL datasource * remove core 22.04 support and installer wrapper script as we don’t ship snaps by default anymore nor installer. * report the status of cloud-init in MoTD if it fails [ Impact ] The impacts are primarly on new rootfses produced by our build pipeline with CPC. It allows CPC also to not special case 24.04 for rootfs publication. So, only new images could see an impact on 24.04 and 22.04 setup, which is easily spottable. The other set of impacts is on systemd units, ensuring that we have the systemd units executed with success as expected and have a working system in the end. Finally, aligning the set of components update in 22.04 which are the defaults tool installed by default, will ensure we are aligning with 24.04. [ Test Plan ] 1. Build new rootfses (with CPC), publish them on cloud-images.ubuntu.com -> we should see one image ending up with "ubuntults" for 22.04 image -> we should have 2 images for 24.04: "ubuntu" and "ubuntults". 2. Build the Ubuntu (24.04), Ubuntu24.04 and Ubuntu22.04 windows package A. New installations: 1. Ship a cloud-init file to touch a file on disk on `%USERPROFILE%\.cloud-init\default.user-data` 2. For each ubuntu application, install them on the machine and create an user on disk -> Check that basic shell commands works -> Check that no MoTD messages complains about cloud-init failure -> Check that the file from the cloud-init profile was applied -> Run systemctl --failed and ensure nothing is listed related to WSL specific configuration itself -> Pro attach the machine and check that it’s attached B. Upgrade testing: Have a 22.04 and 24.04 WSL application installed. On each of them, do the following: 1. apt update && apt full-upgrade 2. wsl --shutdown 3. restart the instance 4. Check the A.2 items all pass. [ Where problems could occur ] Most of the issues could happen on initial boot. It will be really easy to spot any issues there with the previous test plan. On upgrade, the main difference will be in that we replace already shipped systemd unit overrides created by the launcher with some coming from a package. So, the override should still be applied, just in a cleaner way. This is also easily detectable thanks to the previous test plan. The set of updated default tools in 22.04 will show a bigger update than usual, but as we expect most of people to use the "ubuntu" image and also ubuntu24.04 Windows store application, the alignements is risk-less and will give coherence from an user perspective.
