Install genie

https://github.com/arkane-systems/genie

Fix genie on latest Windows 11

See Issue arkane-systems/genie#267

Patch /usr/lib/binfmt.d/WSLInterop.conf:

• From: :WSLInterop:M::MZ::/init:F
• To: :WSLInterop:M::MZ::/init:PF

Auto Start Init Script & Systemd

TLDR: Use /etc/wsl.conf

Add these lines:

[boot] command = /bin/bash /opt/wsl2_init.sh

Add systemctl wrapper

Write the following into /usr/local/bin/systemctl

#!/bin/bash
export PATH=/usr/bin:$PATH # avoid genie recursively call this wrap
genie -c /usr/bin/systemctl "$@"

wsl2_init.sh

#!/bin/bash

# Redirect stdout ( > ) into a named pipe ( >() ) running "tee"
exec > >(tee -a -i /var/log/wsl2_init.log)

# Without this, only stdout would be captured - i.e. your
# log file would not contain any error messages.
# SEE (and upvote) the answer by Adam Spiers, which keeps STDERR
# as a separate stream - I did not want to steal from him by simply
# adding his answer to mine.
exec 2>&1
