Install

• ensure boot mode is set to UEFI in the BIOS (for me: on boot mash Del)
• follow the default instructions
• for bcachefs replace the mount step with:

bcachefs format	--label=nixos --error_action=panic --data_replicas=2 --metadata_replicas=3 --group ssd /dev/sdb1 --group hdd /dev/sda1 --foreground_target ssd	--background_target hdd	--promote_target ssd
mount -t bcachefs /dev/sda1:/dev/sdb1 /mnt

• nano configuration.nix (add git)
• after install:

cd /etc/nixos
git clone https://github.com/tycho01/nix-config.git
mv configuration.nix configuration_.nix
cp -r nix-config .
cp secrets.sample.nix secrets.nix
nano /etc/nixos/users/tycho.nix  # set password
nano /etc/nixos/profiles/os/tychotop.nix  # disable unneeded categories
nixos-rebuild switch
systemctl start display-manager.service

• back up hardware conf to gist: cat /etc/nixos/hardware-configuration.nix
• readd secrets from gist, set up ssh:

sudo chown -R tycho ~
vi /etc/nixos/secrets.nix
mkdir ~/.ssh
cp /etc/nixos/dotfiles/.ssh/id_rsa.pub ~/.ssh/id_rsa.pub
vi ~/.ssh/id_rsa
chmod 0600 ~/.ssh/id_rsa

more commands:

curl -L https://get.oh-my.fish | fish
omf install agnoster
curl -fLo ~/.vim/autoload/plug.vim --create-dirs https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
sudo mkdir /etc/nixos/private
sudo mkdir /etc/nixos/public
# back up dotfiles
sudo mkdir /bkp
sudo cp -r ~/ /bkp
# rebuild
cd ~/Desktop
git clone git@github.com:tycho01/nix-config.git
cd nix-config
cp -r /etc/nixos .
git status
