steam-deck
the steam deck is a gaming device, that happens to also be built on linux. it has an installation of arch linux that you can access. however, by default, it is set to read-only and system updates will remove most of the changes ou make. below are my notes on getting it working as a development machine while insuring you can still play video games.
disabling readonly
note, ths must be run after every system update.
sudo steamos-readonly disable
sudo pacman-key --init
sudo pacman-key --populate holo
sudo pacman -Syu
missing headers like stdio.h
a bunch of C headers were missing. i reinstalled them.
pacman -S glibc linux-api-headers
