 	- add Plasma, Hyprland, and maybe GNOME if I'm feeling silly (I'd probably never actually use it).

+	- The following command is able to successfully show any accumulated state on my system: <pre><code>sudo find  / -xdev \( -path /home -o -path /nix -o -path /boot \)  -prune -o \( -name flatpak -o -name boot.bak -o -path /var/log -o -name .cache \) \( -prune -print \) -o \( -type f \) -print</code></pre>
+	- everything on my system should be declared in this repository or explicitly excluded from the system state
+	- caches should probably be excluded, they exist for a reason and are essentially harmless compared to other forms of state
