+# Secrets
+- 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
