Steamdeck developer setup (Steamos with chroot)

	# Enable sudo by going into Settings/Users and setting a password
	mkdir ~/code/arch
	sudo mount --bind ~/code/arch /mnt # (pacman has trouble measure free disk space without mounting)
	sudo pacstrap -KM /mnt base linux linux-firmware neovim reflector # (note that packages will come from steam's repos, which is also why I used -M to avoid inheriting those)
	sudo arch-chroot /mnt
	reflector > /etc/pacman.d/mirrorlist
	nvim /etc/pacman.conf # and enable parallel downloads, color smile
	# your keyring will probably be wrong, so rm -rf /etc/pacman.d/gpg then pacman-key --init and pacman-key --populate
