---------------
wsl-setup (0.5.8~20.04) focal; urgency=medium
[ Carlos Nihelton ]
* Backport v0.5.8 to Focal to adapt to new Microsoft package format: (LP:
#2115426):
* Releasing this package to Focal for the first time.
- Ship a script that:
1. Copies and registers the Ubuntu font to user's directory.
2. Wait for cloud-init if allowed by systemd and WSL.
3. Request to create an user if not created yet and set it as default.
- Ship static assets like terminal profile and ubuntu icon in .ico
format.
* Updates debian/control dependencies
* Ship wsl-setup under /usr/lib/wsl/ instead of libexec:
This is fixing Microsoft's checker warning.

Title:
[SRU] Backport wsl-setup as new package for Focal
Status in wsl-setup package in Ubuntu:
Fix Released
Status in wsl-setup source package in Focal:
Fix Released
Bug description:
Despite being out of standard support, Ubuntu 20.04 LTS Focal Fossa
remains an important release under WSL. The `wsl-setup` package is
critical for building usable WSL images in the new tar-based format
that no longer requires or depends on MS Store. Building images of
Focal in this new format allows for more adoption of Ubuntu on WSL in
corporate environments, where MS Store is usually restricted or
inaccessible, and that feeds into the adoption of Ubuntu Pro, given
that those running Focal in corporations (due EOL) are likely Pro
subscribers. Thus enabling Focal in the new image format is
strategical for Ubuntu on WSL and Ubuntu Pro.
[Impact]
* `wsl-setup` is exclusive to Ubuntu WSL, so no other Ubuntu product or
experience is affected.
* The mere acceptance of wsl-setup into Focal now is harmless because it will
be a new package, only installable explicitly, not via upgrades.
* Current Ubuntu 20.04 on WSL instances that could get `wsl-setup` installed
by `apt install wsl-setup` won't be functionally affected, as no code will be
executed as part of the installation or later. The same contents of the systemd
overrides shipped within this package are already injected into the rootfs via
the Windows binary that launches the distro instance during the first run, so
they will be just redundant.
* Once we start building new images (in the new tar-based format) with the
planned version of wsl-setup already seeded, then we'll have measurable impacts
of the changes herein proposed, but those would only affect new installations.
The script and systemd overrides herein proposed are the same present in Jammy
and later, thus those releases will be in feature parity in terms of first boot
experience.
[Test Plan]
- Requires Windows 10 or 11 and WSL.
Test 1. Check systemd overrides
* Install a fresh instance of Ubuntu 20.04 on WSL: `wsl.exe --install -d
Ubuntu-20.04`
* Once the setup finishes, verify the system status with `systemctl --failed`
It should print 0 failed units:
u@DESKTOP-551PQ9O:~$ systemctl --failed
UNIT LOAD ACTIVE SUB DESCRIPTION
0 loaded units listed.
* Exit (Ctrl+D), shutdown WSL and restart the instance: `wsl.exe --shutdown;
wsl.exe -d Ubuntu-20.04`
* Once the shell is up and running, verify the system status again with
`systemctl --failed` It should print 0 failed units.
* Enable '-proposed' and apply selective upgrading from it, as described in
https://wiki.ubuntu.com/Testing/EnableProposed.
* Install wsl-setup: `apt install -y wsl-setup/focal-proposed`.
0 loaded units listed.
* Exit (Ctrl+D), shutdown WSL and restart the instance: `wsl.exe --shutdown;
wsl.exe -d Ubuntu-20.04`
* Once the shell is up and running, verify the system status once more with
`systemctl --failed` It should print 0 failed units.
[Where problems could occur]
Existing users manually installing `wsl-setup` could find insufficient
systemd unit overrides leading to a degraded output from `systemctl
--status`. Even under that condition, most users wouldn't notice any
issue in practice. Yet, there is no practical reason for users to
install this package today. Subsequent work is needed to patch livecd-
rootfs and the ubuntu seed for focal to build focal in the new image
format and thus leverage those changes in wsl-setup.
[Other Info]
* `wsl-setup` is already in main for Jammy and later, but never
released into Focal.
