* Maybe rename pkcs7 and public verbs of systemd-keyutil to be more verb like.
+* add "homctl export" and "homectl import" that gets you an "atomic" snapshot
+ of your homedir, i.e. either a tarball or a snapshot of the underlying disk
+ (use FREEZE/THAW to make it consistent, btrfs snapshots)
+
+* maybe introduce a new partition that we can store debug logs and similar at
+ the very last moment of shutdown. idea would be to store reference to block
+ device (major + minor + partition id + diskeq?) in /run somewhere, than use
+ that from systemd-shutdown, just write a raw JSON blob into the partition.
+ Include timestamp, boot id and such, plus kmsg. on next boot immeidately
+ import into journal. maybe use timestamp for making clock more monotonic.
+ also use this to detect unclean shutdowns, boot into special target if
+ detected
+
* sd-boot: do something useful if we find exactly zero entries (ignoring items
such as reboot/poweroff/factory reset). Show a help text or so.
