Setting up auto-mounting for a LUKS-encrypted external drive on NixOS requires coordinating LUKS decryption, udev device detection, and systemd mounting. Here’s how to configure it so the drive automatically decrypts and mounts when connected. First, encrypt the drive if you haven’t already: 1 2 3 4 5 6 cryptsetup luksFormat /dev/sda1 ## Enter password cryptsetup open /dev/sda1 vault dd bs=512 count=4 if=/dev/random of=/root/keyfile.key iflag=fullblock cryptsetup luksAddKey /dev/sda1 /root/keyfile.key sudo mkfs.btrfs -L vault /dev/mapper/vault The keyfile allows automatic decryption without typing a password each time. Your device layout will look like: ...
