Running commands from steamos-devmode script breaks rwfus after reboot

[safijari]

The steamos-devmode script runs the following comments after disabling read-only. I mostly need this in order to restore headers for building packages. When I run this inside rwfus, things work fine until I reboot and then rwfus fails to mount the overlay.

sudo pacman-key --init
sudo pacman-key --populate
sudo pacman -Sy --noconfirm --needed archlinux-keyring
sudo pacman --noconfirm -S $(pacman -Qnkq | cut -d' ' -f1 | sort | uniq)
sudo pacman -S base-devel multilib-devel --needed

This is a known issue and a wontfix. Unfortunately, Rwfus refuses to mount the overlay to avoid bricking someone's SteamOS install:
#20

Please run the command with Rwfus disabled.
