My notes on installing Debian on the nintendo switch, as of middle of 2018.

===== Debian =====
This is bootstrapped from an installed Fedora27.
<code>
dnf -y install debootstrap
mkfs.ext4 /dev/mmcblk0p3
mount /dev/mmcblk0p3 /mnt/mmcblk0p3

debootstrap sid /mnt/mmcblk0p3/ http://ftp.jp.debian.org/debian/
cd /mnt/mmcblk0p3/
echo "proc sid-root/proc proc defaults 0 0" >> etc/fstab 
echo "sysfs /sys sysfs defaults 0 0" >> etc/fstab
echo "/dev/mmcblk0p3 / ext4 defaults 0 0" >> etc/fstab
mount proc proc/ -t proc
mount sysfs sys -t sysfs
cp /etc/hosts etc/
cp /etc/hostname etc/
export LC_ALL=en_US.utf8
chroot . /bin/bash

# now in the debian filesystem
apt-get update
# if it fails, mktemp might be missing, can be copied in from host
cp /usr/bin/mktemp /mnt/mmcblk0p3/usr/bin/

mount -t devpts devpts /dev/pts
echo 'deb http://ftp.jp.debian.org/debian sid main contrib non-free' \
  >>/etc/apt/sources.list
echo 'export PATH=/bin:/sbin:$PATH' >>/root/.bashrc
echo 'alias ll="ls -al"' >>/root/.bashrc

apt-get install locales locales-all
apt-get install openssh-server linux-image-arm64 binutils
apt-get install wpasupplicant network-manager
cp /etc/NetworkManager/system-connections/mynet \
  /mnt/mmcblk0p3/tc/NetworkManager/system-connections/

# now set a password
passwd
# pubkeys should be same as for host
cp -r /root/.ssh/mnt/mmcblk0p3/root/

reboot
# modify your switch linux loader, so partition 3 gets started:
# grep mmcblk0p ./shofel2/usb_loader/switch.scr
setenv bootargs 'root=/dev/mmcblk0p3 rw fbcon=rotate:3 rootwait'

ping switch
# login, and do a first functionality test
ssh root@switch
apt-get update; apt-get install bb
/usr/games/bb

===== Debian Xorg =====
<code>
apt-get install lxde fonts-ipafont-mincho fonts-ipafont-gothic \
  fonts-nanum xfsprogs mesa-utils xfonts-100dpi xfonts-75dpi \
  xfonts-scalable xinput xinit
  
# now we can bring up X
startx

apt-get install firefox fonts-stix fonts-lmodern xvkbd
</code>

===== Debian compiling dri/mesa =====
  * https://dri.freedesktop.org/wiki/Building/
<code>
apt-get install git autoconf xutils-dev wget
apt-get install libtool make flex bison build-essential
apt-get build-dep libdrm mesa

git clone git://anongit.freedesktop.org/mesa/drm
cd drm
./autogen.sh
./configure --enable-tegra-experimental-api --prefix=/usr
make
make install
cd ..

git clone git://anongit.freedesktop.org/git/mesa/mesa
cd mesa
./autogen.sh
# https://github.com/NVIDIA/tegra-rootfs-scripts/blob/master/build-mesa
./configure --prefix=/usr/ --without-dri-drivers \
  --disable-gallium-llvm --with-gallium-drivers=nouveau,tegra \
  --enable-gbm --enable-egl --with-egl-platforms=drm,x11 \
  --enable-gles1 --enable-gles2 --enable-opengl --enable-osmesa \
