How to install TrueNAS SCALE on a partition instead of the full disk

Install TrueNAS SCALE on a partition instead of the full disk

The TrueNAS installer doesn't have a way to use anything less than the full device. This is usually a waste of resources when installing to a modern NVMe which is usually several hundred of GB. TrueNAS SCALE will use only a few GB for its system files so installing to a 16GB partition would be helpful.

The easiest way to solve this is to modify the installer script before starting the installation process.

A Trick To Use mkMerge at The Top Level of a NixOS module

The Setup

I wanted to write a module that generates multiple systemd services and timers to scrub some zfs pools at certain intervals. The default scrub config does not support individual scrub intervals for each pool.

I want the config to look like this:

{
  services.zfs-auto-scrub = {
 tank = "Sat *-*-* 00:00:00";
