Arch Linux

Installation

Followed instructions from here, with the only differences being I installed the most recent version of arch linux arm for rpi 4 from here and the name of the sd card when plugged into my rpi was not sdb but sda. So all refereces were changed accordingly.

Arch Wiki for RPi

https://archlinuxarm.org/wiki/Raspberry_Pi

Wifi

Do all the below as root, since I'm assuming you don't have internet and therefore no sudo yet.

  1. Run wifi-menu -o the -o will...obscure the password, so it's encrypted on disk
  • When it asks for a name for the network give it something simple like: home
  • Once you finish there should be a file: /etc/netctl/home which has the login info (obscured)
  • You should be connected to the wifi now, you can check with: ip a you should see an inet section under wlan0 with an ip address
  1. Enable auto connection at boot with: systemctl enable [email protected]
  • You can check the list of profiles that netctl-auto will try to connect to with netctl-auto list
  • You can choose which profile you connect with via: netctl-auto switch-to <profile_name>

DNS Resolution

It seems our AT&T router was overwriting /etc/resolv.conf when the wifi connected. This lead to domain names not getting resolved. After reading the arch wiki for DNS resolution here, I hard-coded the /etc/resolv.conf file to:

search domain.name
nameserver 8.8.8.8
nameserver 1.1.1.1
nameserver 1.0.0.1

And then set the file to be write protected from programs as the wiki suggests with:

chattr +i /etc/resolv.conf

Stop Audit Logs

Add audit=0 to end of line in /boot/cmdline.txt

Display Setup

Add overscan lines to /boot/config.txt. See video section of RPi arch wiki for some more details

Timezone

User

  1. Add user, -m makes a directory under /home:
useradd -m cary
  1. Add password, user account doesn't come with a password. Creating the password is interactive:
passwd cary
  1. Give sudo permission:
  2. Run visudo as root
  3. Add line:
cary ALL=(ALL) NOPASSWD: ALL
