-    - `/ssh.nix` - all ssh public host and user keys for all `/machines`
 - `/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`

+- consider using headscale
+- Replace luks over tor for remote unlock with luks over tailscale using ephemeral keys
+- Rollover luks FDE passwords
+- /secrets on personal computers should only be readable using a trusted ssh key, preferably requiring a yubikey
+- Rollover shared yubikey secrets
+- offsite backup yubikey, pw db, and ssh key with /secrets access
+
 ### Misc
+- for automated kernel upgrades on luks systems, need to kexec with initrd that contains luks key

-This check prevents the driver from probing with old device trees.
-Allegedly this check is incorrect anyway as the dr_mode should default
