This will create a 16GB swapfile at <code>/var/lib/swapfile</code>. The <code>size</code> value [https://search.nixos.org/options?show=swapDevices.*.size is specified in megabytes]

This will create a 16GB swapfile at <code>/var/lib/swapfile</code>. The <code>size</code> value [https://search.nixos.org/options?show=swapDevices.*.size is specified in megabytes]. This will eventually feed into the <code>/etc/fstab</code> of the built system.

== Swap partition ==

Swap partitions are typically created during the initial disk partitioning phase of a NixOS installation. For instructions on creating swap partitions, see the relevant NixOS manual sections for [https://nixos.org/manual/nixos/stable/#sec-installation-manual-partitioning-UEFI UEFI]/[https://nixos.org/manual/nixos/stable/#sec-installation-manual-partitioning-MBR MBR] partition schemes and [https://nixos.org/manual/nixos/stable/#sec-installation-manual-partitioning-formatting formatting].

Swap partitions can be defined in <code>configuration.nix</code> like above or (if GPT) be automatically discovered by <code>systemd-gpt-auto-generator(8)</code>. Using the former allows you to have some control over swap mounting options and to enable features such as encrypted swap.
