# Install nix minimal with bcachefs filesystem
|
|
|
|
- optional encryption
|
|
- optional auto unlock with USB key
|
|
- custom iso installer
|
|
- `nix build .\#packages.x86_64-linux.iso-minimal-stable`
|
|
|
|
## Format main drive with boot partition
|
|
|
|
### Partition with GPT
|
|
|
|
```sh
|
|
DEVICE=sda
|
|
parted /dev/$DEVICE -- mklabel gpt
|
|
parted /dev/$DEVICE -- mkpart ESP fat32 1MB 2GB
|
|
parted /dev/$DEVICE -- set 1 esp on
|
|
# TODO make swap partition instead here? Bcachefs not working with swapfile
|
|
parted /dev/$DEVICE -- mkpart PRIMARY 2GB 100%
|
|
```
|
|
|
|
### Format partitions
|
|
|
|
- boot
|
|
|
|
```sh
|
|
BOOT=sda1
|
|
mkfs.fat -F 32 -n BOOT /dev/$BOOT
|
|
```
|
|
|
|
- primary
|
|
|
|
```sh
|
|
PRIMARY=sda2
|
|
keyctl link @u @s
|
|
bcachefs format --label=nixos --encrypted /dev/$PRIMARY
|
|
bcachefs unlock /dev/$PRIMARY
|
|
```
|
|
|
|
### Setup subvolumes
|
|
|
|
```sh
|
|
# keyctl link @u @s
|
|
# TODO check this is it 7 or 8 for print?
|
|
U=$(lsblk -o fsType,uuid | grep bcachefs | awk '{print $2}')
|
|
echo $U
|
|
mount /dev/disk/by-uuid/$U /mnt
|
|
|
|
bcachefs subvolume create /mnt/@root
|
|
bcachefs subvolume create /mnt/@nix
|
|
bcachefs set-file-option /mnt/@nix --compression=zstd
|
|
bcachefs subvolume create /mnt/@snapshots
|
|
bcachefs set-file-option /mnt/@snapshots --compression=zstd
|
|
bcachefs subvolume create /mnt/@swap
|
|
bcachefs set-file-option /mnt/@swap --nocow
|
|
bcachefs subvolume create /mnt/@persist
|
|
|
|
umount /mnt
|
|
```
|
|
|
|
> Tip `getfattr -d -m '^bcachefs\.' filename`
|
|
|
|
> Note: Format any additional drives if you need to
|
|
|
|
### Mount subvolumes
|
|
|
|
```sh
|
|
DEV_B="/dev/disk/by-uuid/"$(lsblk -o NAME,UUID | grep $BOOT | awk '{print $2}')
|
|
DEV_P="/dev/disk/by-uuid/"$(lsblk -o NAME,UUID | grep $PRIMARY | awk '{print $2}')
|
|
mount -t bcachefs -o X-mount.subdir=@root $DEV_P /mnt
|
|
mount -t vfat $DEV_B /mnt/boot --mkdir
|
|
mount -t bcachefs -o X-mount.mkdir,X-mount.subdir=@nix,relatime $DEV_P /mnt/nix
|
|
mount -t bcachefs -o X-mount.mkdir,X-mount.subdir=@snapshots,relatime $DEV_P /mnt/.snapshots
|
|
mount -t bcachefs -o X-mount.mkdir,X-mount.subdir=@swap,noatime $DEV_P /mnt/.swap
|
|
mount -t bcachefs -o X-mount.mkdir,X-mount.subdir=@persist $DEV_P /mnt/persist
|
|
```
|
|
|
|
### Generate hardware config
|
|
|
|
```sh
|
|
nixos-generate-config --root /mnt
|
|
```
|
|
|
|
- Copy useful bits out into real config in repo
|
|
- Run nixos-install
|
|
|
|
```sh
|
|
nixos-install --flake "git+https://git.joshuabell.xyz/ringofstorms/dotfiles?dir=hosts/i001#i001"
|
|
# nh os switch "git+https://git.joshuabell.xyz/ringofstorms/dotfiles?dir=hosts/i001#i001"
|
|
```
|
|
|
|
or from host machine? TODO haven't tried this fully
|
|
|
|
```sh
|
|
NIX_SSHOPTS="-i /run/agenix/nix2nix" sudo nixos-rebuild switch --flake "git+https://git.joshuabell.xyz/ringofstorms/dotfiles?dir=hosts/i001#i001" --target-host luser@10.12.14.157 --build-host localhost
|
|
|
|
```
