These are my configurations for nixos. You are free to use it, however it may be best for you to fork and make your own. These are my configurations for nixos. You are free to use it, however it may be best for you to fork and make your own.
## Installing ## Installing
In my experience, you need a larger disk size for the nix store on the installer than is created. As such, I use a NFS mount with a swap file. If you are installing using an USB stick, you can probably place a swap file there. In my experience, you need a larger disk size for the nix store on the installer than is created. As such, I use a swap file/drive, recommended separate drive from the one being installed to.
### Swap example.
```bash ```bash
nix-shell -p git nfs-utils mkdir /mnt/usb
mkdir /mnt/merged mount /dev/sdb1 /mnt/usb
mount.nfs 10.0.0.5:/mnt/merged /mnt/merged fallocate -l 30G /mnt/usb/swap
mkdir /mnt/merged/nixos-tmp chmod 600 /mnt/usb/swap
fallocate -l 30G /mnt/merged/nixos-tmp/swap mkswap /mnt/usb/swap
chmod 600 /mnt/merged/nixos-tmp/swap swapon /mnt/usn/swap
mkswap /mnt/merged/nixos-tmp/swap
swapon /mnt/merged/nixos-tmp/swap
mount -o remount,size=20G,noatime /nix/.rw-store mount -o remount,size=20G,noatime /nix/.rw-store
```
### The install process.
After setting up the extra swap space, clone and enter the nixos repo.
```bash
nix-shell -p git
git clone --recursive https://github.com/GRMrGecko/nixos.git git clone --recursive https://github.com/GRMrGecko/nixos.git
``` cd nixos/
```
After you get into the repo, configure the machine to your liking.
```bash
./configure.sh
```
After configuring, install. You can define a tmpdir as the USB drive with `TMPDIR=/mnt/usb` if you want to reduce load on RAM.
```bash
./install.sh --disk main /dev/sda
```
After install is complete, you can then rsync the nixos dir to the user account on the install:
```bash
nix-shell -p rsync
mount -o compress=zstd /dev/mapper/crypted /mnt/hdd
rsync -av /root/nixos/ /mnt/hdd/home/grmrgecko/nixos/
```
