Configuration
Swap on NixOS is set with the option swapDevices on /etc/nixos/hardware-configuration.nix.
Add a Swapfile
Add a swapfile with the following :
swapDevices = [ {
device = "/var/lib/swapfile";
size = 16*1024;
} ];
Disable swap
To remove all swap devices from NixOS, set the following to remove the swap partition or file from being included in /etc/fstab.
swapDevices = lib.mkForce [ ];
If you are using GPT partitioning tables, systemd-gpt-auto-generator(8) will still mount your swap partition automatically. You must therefore turn on attribute 63 on your partition in the partition table. This can be done with gptfdisk or similar:
gdisk /dev/sda
x
a
<partition number>
63
<enter>
