This introduces the beginnings of an image definition for Windows
Subsystem for Linux (WSL).
The package list is based on the core and standard grouplists. Some
packages, like the kernel, dracut, and so on, are omitted as they are
unnecessary. Others, like audit, don't work in the environment. Finally,
many packages are omitted since I thought "people probably won't want
that", so the package list is completely up for debate. This is just a
reasonable starting point that works.
Build/test instructions:
To build the tarball:
$ ./kiwi-build --image-profile=WSL-Base --image-type=tbz --output-dir=./build/
Get it to a Windows host with WSL installed. To boot it with cgroupsv2,
add the following to `.wslconfig` in the Windows host home folder:
[wsl2]
kernelCommandLine=systemd.unified_cgroup_hierarchhy=1 cgroup_no_v1=all
This assumes the latest WSL release is installed, at least version 2.4.4:
$ wsl --install --from-file .\path\to\the\fedora.tar.xz
Alternatively, if you're using something prior to version 2.4.4:
$ wsl --import --version=2 Fedora C:\path\to\storage\Fedora\ .\path\to\the\fedora.tar.xz
Finally, run it with:
$ wsl -d Fedora
If you are using 2.4.4+, you will be prompted for a username and then
dropped into an interactive shell with that user and passwordless sudo
access.
If you're using an older version, you need to do:
$ wsl -d Fedora -u root
# /usr/libexec/wsl/oobe.sh

Gary Buhrmaster noticed gzip was missing from the Fedora 40 container.
An extremely quick and gross diff produced by doing:
podman run -it --rm --entrypoint /usr/bin/rpm fedora:39 -qa \
| sort | uniq | awk '{ split($0,a,"-[0-9]"); print a[1] }' > f39.txt
shows the following for Fedora Minimal 39 -> 40:
-abattis-cantarell-vf-fonts
+audit-libs
-default-fonts-core-sans
-fonts-filesystem
-google-noto-fonts-common
-google-noto-sans-mono-vf-fonts
-google-noto-sans-vf-fonts
-google-noto-serif-vf-fonts
-gpg-pubkey
+gpg-pubkey-a15b79cc
+json-c
-langpacks-core-en
-langpacks-en
-langpacks-fonts-en
+libcap-ng
+libeconf
-libsigsegv
+libtool-ltdl
+pam-libs
-systemd-libs
-util-linux-core
-zlib
+zlib-ng-compat
For Fedora 39 -> 40:
-authselect
-authselect-libs
-cracklib
-gpg-pubkey
+gpg-pubkey-a15b79cc
-gzip
-libdb
-libpwquality
-libsigsegv
+libtool-ltdl
-pam
-sudo
-systemd-libs
-util-linux-core
-zlib
+zlib-ng-compat
This adds gzip and sudo back to the non-minimal container, as well as
bzip2, xz, and zstd to round out the set of [de]compression tools.
Azure provides an optional "Accelerated Networking" feature. Enabling
this feature when creating a VM enables SR-IOV and provides the guest
with a virtual function.
Supporting this requires two changes. Firstly, the kernel-modules
package is required as it contains the Mellanox drivers required for the
VF provided to the guest. Secondly, the interface needs to be ignored by
NetworkManager or it'll try and fail to bring up the device and the VM
will be unreachable except by serial console. If this is observed, it's
likely new hardware has been deployed and additional drivers need to be
added to the NetworkManager config.
See https://learn.microsoft.com/en-us/azure/virtual-network/accelerated-networking-overview
for details.
