# nixos
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
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 mkdir /mnt/usb mount /dev/sdb1 /mnt/usb fallocate -l 30G /mnt/usb/swap chmod 600 /mnt/usb/swap mkswap /mnt/usb/swap swapon /mnt/usn/swap 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 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/ ```
