Athena OS

Testing

This document shows a list of test cases that can be used to check the correctness of the environment.

Manual environment installation

Boot into Athena Live Environment by using Athena ISO.

Create the needed partitions.

Terminal window
sudo -i
Terminal window
parted /dev/sda -- mklabel gpt
parted /dev/sda -- mkpart ESP fat32 1MiB 512MiB
parted /dev/sda -- set 1 esp on
parted /dev/sda -- mkpart swap linux-swap 512MiB 8GB
parted /dev/sda -- mkpart primary 8GB 100%

The created partitions are:

  • /dev/sda1 -> Boot partition
  • /dev/sda2 -> Swap partition
  • /dev/sda3 -> Root partition

Format the partitions:

Terminal window
mkfs.btrfs -L arch /dev/sda3
mount /dev/disk/by-label/arch /mnt

Format the boot partition:

Terminal window
mkfs.fat -F 32 -n BOOT /dev/sda1

and mount it:

Terminal window
mount --mkdir /dev/sda1 /mnt/boot

Format the swap partition

Terminal window
mkswap -L swap /dev/sda2
swapon /dev/sda2

If you need to test the deployment of an Arch environment, please follow the Arch Installation section, otherwise, for Nix environment, follow the Nix Installation section.

Minimal Arch Installation

Now proceed to the minimal Arch installation:

Terminal window
pacman-key --init
pacman-key --populate
pacstrap /mnt base
genfstab -U /mnt >> /mnt/etc/fstab

Now, take the UUID of the root partition (i.e., sda3) that will be used later:

Terminal window
lsblk -no name,uuid

and you will get:

sda
|-sda1      733f5e5e-e53e-48aa-b975-3176e685c199
|-sda2      2c29bffd-a015-4485-9571-72fb1c5102f8
`-sda3      7ab2a484-95a8-4ded-b483-b0bf086c7e41
  `-crypted 506a895e-2e87-4955-ba47-8c25029b994d

Enter in the mounted partition by arch-chroot:

Terminal window
arch-chroot /mnt
Terminal window
pacman -S nano mkinitcpio linux-lts linux-lts-headers grub efibootmgr

Then, edit /etc/default/grub and add the rd.luks.name to GRUB_CMDLINE_LINUX_DEFAULT as:

GRUB_CMDLINE_LINUX_DEFAULT="rd.luks.name=7ab2a484-95a8-4ded-b483-b0bf086c7e41=crypted root=/dev/mapper/crypted loglevel=3 quiet"

Save it and run:

Terminal window
echo "en_US.UTF-8 UTF-8" > /etc/locale.gen
locale-gen
echo "LANG=en_US.UTF-8" > /etc/locale.conf
ln -sf /usr/share/zoneinfo/Europe/Zurich /etc/localtime
echo "athenaos" > /etc/hostname
echo "KEYMAP=us" > /etc/vconsole.conf

Edit /etc/mkinitcpio.conf and edit HOOKS as:

HOOKS=(base systemd autodetect modconf kms keyboard sd-vconsole sd-encrypt block filesystems fsck)

Save it and run:

Terminal window
mkinitcpio -P
sed -i "s/#GRUB_ENABLE_CRYPTODISK=.*/GRUB_ENABLE_CRYPTODISK=y/g" /etc/default/grub
Terminal window
grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=GRUB
Terminal window
grub-mkconfig -o /boot/grub/grub.cfg
passwd
exit
umount -R /mnt
reboot

Nix Installation

Add Nix channels as:

Terminal window
nix-channel --add https://nixos.org/channels/nixos-unstable nixpkgs
nix-channel --update

Then, generate the hardware configuration and get the Athena Nix configuration:

Terminal window
mkdir -p /mnt/etc/nixos
nix-shell -p nixos-install-tools --command "nixos-generate-config --root /mnt"
curl -o /tmp/athena-nix.zip https://codeload.github.com/Athena-OS/athena-nix/zip/refs/heads/main
unzip /tmp/athena-nix.zip -d /tmp/
cp -rf /tmp/athena-nix-main/nixos/home-manager /tmp/athena-nix-main/nixos/hosts /tmp/athena-nix-main/nixos/modules /tmp/athena-nix-main/nixos/pkgs /tmp/athena-nix-main/nixos/users /tmp/athena-nix-main/nixos/configuration.nix /tmp/athena-nix-main/nixos/default.nix /mnt/etc/nixos/
sed -i "s/\/etc\/nixos\/hardware-configuration.nix/.\/hardware-configuration.nix/g" /mnt/etc/nixos/configuration.nix

If you are in a GRUB BIOS/Legacy environment, run:

Terminal window
sed -i "s/bootloader = \"systemd\"/bootloader = \"grub\"/g" /mnt/etc/nixos/configuration.nix

Finally, run the Athena Nix installation:

Terminal window
nix-shell -p nixos-install-tools --run "nixos-install --no-root-password --cores 2 --max-jobs 16 --keep-going"
