I am new to NixOS, I used this guide for setting up root impermanence: Nixos and Erasing My Darlings · hanckmann.com
The Problem
home-manager-user.service fails to symlink files, due to my home folder being owned by root.

Below is how I setup my user. At first I didn’t specify a uid, and then when I did it fixed it. But now as I was tinkering with setting up zsh in another module, the problem came back.It almost feels like a race condition?
users.users.${cfg.name} =
{
isNormalUser = true;
inherit (cfg) name initialHashedPassword;
home = "/home/${cfg.name}";
group = "users";
ignoreShellProgramCheck = true;
uid = 1000;
extraGroups = [ "wheel" "audio" "sound" "video" "networkmanager" "input" "tty" "docker" ] ++ cfg.extraGroups;
} // cfg.extraOptions;
What i’ve tried:
Setting uid=1000 as an option when mounting /home
Manually chown the home dir.
Set users.users..createHome = true;
What could/is the cause of this and how can I fix it?
Looking forward to hear any ideas.
Thanks in advance.
