Features:
+* busctl: maybe expose a verb "ping" for pinging a dbus service to see if it
+ exists and responds.
+
* homed: add homed.conf setting DefaultStorage= or so
* homed: maybe pre-create ~/.cache as subvol so that it can have separate quota
thus allows defining OS images which can be A/B updated and we default to the
newest version automatically, both in nspawn and in sd-boot
-* drop sd_bus_message_set_priority() from sd-bus API and documentation as much
- as we can, it's a kdbus left-over and unlikely to come back on AF_UNIX, since
- it's not really implementable there.
-
* cryptsetup/homed: also support FIDO2 HMAC password logic for unlocking
devices. (see: https://github.com/mjec/fido2-hmac-secret)
