 ## IMPROVEMENTS:
+- servo: expand /boot to 2 GiB like all other hosts
+- moby: port to systemd-boot
+- image builder: make sure i distribute EFI/BOOT/BOOTX64.efi (as systemd-boot)
 - sane-deadlines: show day of the week for upcoming items
   - and only show on "first" terminal opened; not on Ctrl+N terminals
 - curlftpfs: replace with something better
