+# My NixOS configurations
+
+### Source Layout
+- `/common` - common configuration imported into all `/machines`
+    - `/boot` - config related to bootloaders, cpu microcode, and unlocking LUKS root disks over tor
+    - `/network` - config for tailscale, and NixOS container with automatic vpn tunneling via PIA
+    - `/pc` - config that a graphical desktop computer should have. Use `de.enable = true;` to enable everthing.
+    - `/server` - config that creates new nixos services or extends existing ones to meet my needs
+- `/machines` - all my NixOS machines along with their machine unique configuration for hardware and services
+    - `/kexec` - a special machine for generating minimal kexec images. Does not import `/common`
+- `/secrets` - encrypted shared secrets unlocked through `/machines` ssh host keys

+- for automated kernel upgrades on luks systems, need to kexec with initrd that contains luks key
