+  verity, but rest doesn't matter), LOCKEDDOWN (to require that everything is
+  on signed verity, except for ESP), SUPERLOCKDOWN (like LOCKEDDOWN but ESP not
+  allowed). And then maybe some flavours of that that declare what is expected
+  from home/srv/var… Then, add a new cmdline flag to all tools that parse such
+  images, to configure this. Also, add a kernel cmdline option for this, to be
+  honoured by the gpt auto generator.

+* nspawn: maybe optionally insert .nspawn file as GPT partition into images, so
+  that such container images are entirely stand-alone and can be updated as
+  one.

 * we probably should extend the root verity hash of the root fs into some PCR
   on boot. (i.e. maybe add a crypttab option tpm2-measure=8 or so to measure it
   into PCR 8)
