* .automount units may now be transient.
* Mount and automount units may now be created transiently
(i.e. dynamically at runtime via the bus API, instead of requiring
unit files in the file system).
* systemd-mount is a new tool which wraps mount(8) to pull in
additional dependencies through transient .mount and .automount
units. For example, this automatically runs fsck on the block device
before mounting, and allows the automount logic to be used.
* systemd-mount is a new tool which may mount file systems – much like
mount(8), optionally pulling in additional dependencies through
transient .mount and .automount units. For example, this tool
automatically runs fsck on a backing block device before mounting,
and allows the automount logic to be used dynamically from the
command line for establishing mount points. This tool is particularly
useful when dealing with removable media, as it will ensure fsck is
run – if necessary – before the first access and that the file system
is quickly unmounted after each access by utilizing the automount
logic. This maximizes the chance that the file system on the
removable media stays in a clean state, and if it isn't in a clean
state is fixed automatically.
* LazyUnmount=yes option for mount units has been added to expose the
umount --lazy option. Similarly, ForceUnmount=yes exposes the --force

* When operating on GPT disk images for containers, systemd-nspawn will
now mount the ESP to /boot or /efi according to the same rules as PID
1 running on a host. This allows tools like "bootctl" to operate
correctly within such containers, in order to make container images
bootable on physical systems.

sd_bus_track_get_recursive(), sd_bus_track_count_name(),
sd_bus_track_count_sender(). They permit usage of sd_bus_track peer
tracking objects in a "recursive" mode, where a single client can be

process using sd-bus automatically exit if the bus connection is
severed.
* Bus clients of the service manager may now "pin" loaded units into
memory, by taking an explicit reference on them. This is useful to
ensure the client can retrieve runtime data about the service even
after the service completed execution. Taking such a reference is
available only for privileged clients and should be helpful to watch
running services in a race-free manner, and in particular collect
information about exit statuses and results.
