* busctl: maybe expose a verb "ping" for pinging a dbus service to see if it
exists and responds.
-* when systemd-nspawn and suchlike dissect an OS image, and there are multiple
- root partitions, do an strverscmp() on the partition label and boot
- first. That is inspired how sd-boot figures out which kernel to boot, and
- 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
-
* systemd-gpt-auto should probably set x-systemd.growfs on the mounts it
creates
* journalctl: make sure -f ends when the container indicated by -M terminates
-* mount: automatically search for "main" partition of an image has multiple
- partitions
-
* in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
find a way to map the User=/Group= of the service to the right name. This way
a user/group for a service only has to exist on the host for the right
