# NixOS Build Spec (sam-4screen-desktop)
|
||||
|
||||
## Disk / Boot (DO NOT BRICK WINDOWS)
|
||||
## Disk / Boot (WIPE ENTIRE NVMe DISK)
|
||||
|
||||
Target disk: /dev/nvme0n1
|
||||
- Size: 953.87 GiB (1024209543168 bytes), 2000409264 sectors
|
||||
- Model: PM951 NVMe SAMSUNG 1024GB
|
||||
- NVMe serial: S2FZNXAH301424
|
||||
- NVMe WWID: nvme.144d-2020202020205332465a4e584148333031343234-504d393531204e564d652053414d53554e4720313032344742-00000001
|
||||
- Sector size (logical/physical): 512 bytes / 512 bytes
|
||||
Install target is NVMe only. Do not select /dev/sdX devices in the installer.
|
||||
Device names like /dev/sdb, /dev/sdc can change across boots; always rely on UUID/label.
|
||||
|
||||
NOTE: GPT partition table entries may not be stored/printed in on-disk (Start sector) order.
|
||||
- Do NOT rely on the order shown by some tools.
|
||||
- Always identify partitions by (partition number + type + UUID/label).
|
||||
- If you need the physical order, sort by the “Start” sector column (e.g. `fdisk -l` output).
|
||||
DECISION (CONFIRMED):
|
||||
- Do NOT keep Windows.
|
||||
- Wipe the entire /dev/nvme0n1 (all existing partitions will be deleted/overwritten).
|
||||
|
||||
Verification commands (run before formatting):

||||
Installer safety:
|
||||
- Install target is NVMe only. Do not select /dev/sdX devices in the installer.
|
||||
- Device names like /dev/sdb, /dev/sdc can change across boots; always rely on UUID/label when mounting non-target disks.
|
||||
|
||||
Verification commands (run before wiping, if you want one last check):
|
||||
- `lsblk -o NAME,SIZE,TYPE,FSTYPE,LABEL,UUID,MOUNTPOINTS`
|
||||
- `sudo fdisk -l /dev/nvme0n1` (interpret physical order by sorting on Start)
|
||||
- `sudo blkid /dev/nvme0n1p1 /dev/nvme0n1p3 /dev/nvme0n1p4 /dev/nvme0n1p5`
|
||||
- `sudo fdisk -l /dev/nvme0n1`
|
||||
|
||||
KEEP (do not format):
|
||||
- /dev/nvme0n1p1 (EFI vfat) UUID=94CC-9DA4 (~99MiB, FAT32, mounted at /boot/efi)
|
||||
- /dev/nvme0n1p2 (MS reserved) (~15MiB)
|
||||
- /dev/nvme0n1p3 (Windows NTFS) UUID=8294CD2994CD2111 (~503GiB)
|
||||
- /dev/nvme0n1p4 (Windows recovery NTFS) UUID=6E1AA32B1AA2EEF1 (~529MiB)
|
||||
Boot method:
|
||||
- UEFI
|
||||
- Bootloader: systemd-boot

WIPE + install NixOS here:

|
||||
Filesystem / layout:
|
||||
- Root filesystem: Btrfs (with subvolumes)
|
||||
- Encryption: none
|
||||
- Swap: zram
|
||||
- Hibernate: no
|
||||
- /home: Btrfs subvolume
|
||||
|
||||
Partitioning approach:
|
||||
- Manual in the installer (no disko)
|
||||
|
||||
Recommended layout:
|
||||
- New GPT on /dev/nvme0n1
|
||||
- EFI System Partition (vfat), mounted at /boot
|
||||
- Btrfs partition for the rest
|
||||
- Subvolume @ mounted at /
|
||||
- Subvolume @home mounted at /home
|
||||
|
||||
IMPORTANT:
|
||||
- `hosts/sam-4screen-desktop/hardware-configuration.nix` is currently a placeholder.
|
||||
- During install after mounting to /mnt:
|
||||
1) Run: `nixos-generate-config --root /mnt`
|
||||
2) Copy: `/mnt/etc/nixos/hardware-configuration.nix` into:
|
||||
`hosts/sam-4screen-desktop/hardware-configuration.nix`

## Networking
|
||||
- Use NetworkManager
|
||||
- Static IPv4 for wired: enp0s31f6 = 192.168.20.27/24
|
||||
- Gateway: 192.168.20.1
|
||||
- DNS: 192.168.20.35, 192.168.20.13
|
||||
|
||||
Static IPv4 policy (CONFIRMED):
|
||||
- Static IPv4 should be applied to Wi-Fi SSID:
|
||||
- SSID / connection id: "Aussie Broadband 8729"
|
||||
- Interface: wlp4s2
|
||||
- IP: 192.168.20.27/24
|
||||
- Gateway: 192.168.20.1
|
||||
- DNS: 192.168.20.35, 192.168.20.13
|
||||
- Wired enp0s31f6: no static IP required for now
|
||||
|
||||
Secrets policy:
|
||||
- Do not commit Wi-Fi PSKs to git.
|
||||
- Static IP enforcement is implemented via a NetworkManager dispatcher script.
|
||||
|
||||
## Data drive mount
|
||||
- Integral300 ext4 UUID=27febd74-20aa-4a3a-92c1-6fdd1ad7e88e
|
||||
- Mountpoint on NixOS: /data (preferred)
|
||||
|
||||
## Dotfiles policy
|
||||
- Dotfiles live on the installed system at: ~/dotfiles
|
||||
- Do not depend on /data for dotfiles.
|
||||
|
||||
## Desktop
|
||||
- Primary compositor: Niri
|
||||
- Display/login manager: greetd + tuigreet
