Upgrade LineageOS with Magisk

WARNING: tested only on my setup (LineageOS 18.1 on instantnoodle), other setups may break and brick the device!

Step-by-step instructions (for reinstalling patched boot.img for Magisk):

upgrade LineageOS to the latest by the standard way in Android GUI (download + install + reboot)
if using not the latest Magisk: wipe old (possibly hidden) Magisk app then install the up-to-date one from the official Magisk github repo
~~install (git clone) payload_dumper from GitHub (in Termux or in an SSH session on the Android device) for the 1st time, or update (git pull) later~~
~~the Android terminal session: wget the same LineageOS nightly image installed in step 1 from https://download.lineageos.org/~~

QEMU-KVM in Arch Linux

Check Virtualization Support

lscpu | grep -i Virtualization

VT-x for Intel
AMD-Vi for AMD

Ensure that your kernel includes KVM modules

True Color (24-bit) and italics with alacritty + tmux + vim (neovim)

This should make True Color (24-bit) and italics work in your tmux session and vim/neovim when using Alacritty (and should be compatible with any other terminal emulator, including Kitty).

Testing colors

Running this script should look the same in tmux as without.

Instructions to hack up WSL2 on Windows 10 Build 18917 to run k3s (Kubernetes) and rio

Install WSL2

https://docs.microsoft.com/en-us/windows/wsl/wsl2-install

I already had Ubuntu-18.04 installed in wsl 1. So I just did wsl --set-version Ubuntu-18.04 2

Compile Kernel

Using Ubuntu 18.04 (I'm sure any distro will work), inside WSL2 download https://thirdpartysource.microsoft.com/download/Windows%20Subsystem%20for%20Linux%20v2/May%202019/WSLv2-Linux-Kernel-master.zip and extract to a folder. The latest version of the kernel source is available at (https://github.com/microsoft/WSL2-Linux-Kernel)
