# Dualbooting NixOS and FreeBSD
|
||
|
|
|
||
|
|
Out of curiosity, I decided to dual-boot NixOS and FreeBSD on my laptop, sharing
|
||
|
|
one disk. I document the process here for future reference:
|
||
|
|
|
||
|
|
## Linux install
|
||
|
|
|
||
|
|
First, flash a stick with NixOS, then boot into it, wipe your disk, create two
|
||
|
|
partitions, one being boot, the other your main NixOS partition. Then, follow
|
||
|
|
these commands:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
sudo su
|
||
|
|
|
||
|
|
cryptsetup luksFormat /dev/diskname/partition
|
||
|
|
|
||
|
|
cryptsetup open /dev/diskname/partition crypt
|
||
|
|
|
||
|
|
mkfs.btrfs -L nixos /dev/mapper/crypt
|
||
|
|
|
||
|
|
mount /dev/mapper/crypt /mnt
|
||
|
|
|
||
|
|
btrfs create subvolume /mnt/nix
|
||
|
|
btrfs create subvolume /mnt/home
|
||
|
|
btrfs create subvolume /mnt/persist
|
||
|
|
|
||
|
|
mkdir /mnt/boot
|
||
|
|
mount /dev/partition # boot partition
|
||
|
|
```
|
||
|
|
|
||
|
|
Then, copy [my nixos flake](https://github.com/bloxx12/nichts) to `/mnt`, you
|
||
|
|
can remove it from there later on.
|
||
|
|
|
||
|
|
```bash
|
||
|
|
git clone https://github.com/bloxx12/nichts /mnt
|
||
|
|
```
|
||
|
|
|
||
|
|
In there, change the file system uuids to the correct ones, you can see them
|
||
|
|
using
|
||
|
|
|
||
|
|
```bash
|
||
|
|
sudo blkid
|
||
|
|
```
|
||
|
|
|
||
|
|
Then, install NixOS itself:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
nixos-install --impure --flake /mnt/nichts#<hostname> -j 1 --cores 2
|
||
|
|
```
|
||
|
|
|
||
|
|
Wait for that to finish, then reboot.
|
||
|
|
|
||
|
|
If your system works, great! if not, redo from the beginning.
|
||
|
|
|
||
|
|
After that, set up FreeBSD the following way:
|
