My personal cheatsheet for Nix OS Installation.

• download latest ISO and verify checksums
  • Download Nix OS (I prefer Minimal ISO)
• scripts to install, snapper setup
  • Install Scripts

I usually set bigger font with setfont ter-v32n :

• sudo -i (can use nixos-help for manual)
• TODO!! update for networking

connecting with Ethernet or mobile USB tethering is enabled by default

I install Nix on my ~233G SSD.

• i prefer gdisk
• ef00 for fat32 fstype

• nvme0n1p2 remaining size. ~232G

  later set up zram

install git, neovim

nix-env -f '<nixpkgs>' -iA neovim
nix-env -f '<nixpkgs>' -iA git

git clone https://github.com/alokshandilya/nixos-install-scripts.git

all scripts are executable but still have a glance on the commands and modify accordingly

./1-format_mount.sh

• run 🏃./1-format_mount.sh
  • formats the partitions
  • makes btrfs subvolumes
  • mounts the partitions
  • generates fstab based on UUIDs (remove subvolid later from /etc/fstab)

• nixos-generate-config --root /mnt

• nvim /mnt/etc/nixos/configuration.nix, manually add mount options

• nixos-install

• nixos-generate-config --show-hardware-config doesn't detect mount options automatically, so to enable compression, you must specify it and other mount options in a persistent configuration:

fileSystems = {
  "/".options = [ "defaults,noatime,compress=zstd,discard=async,space_cache=v2,autodefrag" ];
  "/home".options = [ "defaults,noatime,compress=zstd,discard=async,space_cache=v2,autodefrag" ];
  "/nix".options = [ "defaults,noatime,compress=zstd,discard=async,space_cache=v2,autodefrag" ];
  "/.snapshots".options = [ "defaults,noatime,compress=zstd,discard=async,space_cache=v2,autodefrag" ];
};

• TODO!!! update it with your nix configuration file
• update the configuration file
• If you want to use GRUB, set boot.loader.grub.device to nodev and boot.loader.grub.efiSupport to true. With systemd-boot, you should not need any special configuration to detect other installed systems. With GRUB, set boot.loader.grub.useOSProber to true, but this will only detect windows partitions, not other Linux distributions. If you dual boot another Linux distribution, use systemd-boot instead.

./2-base-install.sh

• edit /etc/default/grub
  • blkid > blkit.txt :vs :bp :bn in vim /etc/default/grub
    • note nvme0n1p2 (partition with subvolumes) UUID
  • GRUB_CMDLINE_LINUX=cryptdevice=UUID=xxxxx:cryptroot rootfstype=btrfs
  • grub-mkconfig -o /boot/grub/grub.cfg

run 🏃 3-touchpad.sh if to use Window Manager (on laptop) to enable trackpad reverse scrolling etc.

• edit /etc/mkinitcpio.conf
  • MODULES=(btrfs crc32c-intel intel_agp i915 nvidia)
  • HOOKS=(.... encrypt filesystems fsck)
• mkinitcpio -P
• do exit , umount -a , reboot

• connect to wifi with nmtui

./4-dwm-install.sh

• reboot
• run 🏃5-packages-AUR.sh
  • AURs are commented
• install rest of the packages

cd ~/arch-install-scripts
paru -S stow
paru -S --needed - < pkglist.txt

• 4-dwm-install script also installs paru

• setup nvim

  • v alias for nvim

• setup sdkman for fish
