- ### Script for installing ArchLinuxARM on asus c101pa 256GB sd card
- ###
- ### Aims to replicate gdm login loop, dated 20th September 2019
- ###
- ### CREDIT to bikochan https://github.com/bikochan/c101pa
- ###
- ### 1. Insert 256GB sd card
- ### 2. Ctrl-d
- ### 3. cp install.sh /tmp
- ### cd /tmp
- ### sudo su
- ### bash install.sh
- ### reboot
- ### 4. Ctrl-u
- ### 5. login as root
- ### 6. sudo wifi-menu
- ### 7. bash setup.sh
- ###
- ### PREREQUISITES:
- ###
- ### 1) Assumes that ArchLinuxARM-gru-latest.tar.gz is present on USB at
- ###
- ### /media/removable/XXXX
- ###
- ### 3) Assumes that setup.sh is present at
- ###
- ### /home/user/XXXX/Downloads/
- ###
- ### 2) Assumes that a 256GB sd card is present
- ###
- ### ISSUES:
- ###
- ### 1) As of December 2019, wifi-menu is not installed by default in the base system
- ### and appears to have been removed from ArchLinuxARM-gru-latest.tar.gz
- ###
- ### 2) To bypass login loop, edit /etc/gdm/custom.conf as described in the gdm docs
