Features:
+* hwdb: add a new field that can be used to mark network devices where only
+ ipv4ll/ipv6ll makes sense, i.e. which should not expect to be connected to
+ the internet, i.e. for direct host-to-host connection. Set it for thunderbolt
+ networking, and for "laplink"-style network cables. Then make netword match
+ against that prop in a .network file we ship by default. Would be
+ particularly useful in storage target mode (i.e. NVME-TCP) modes.
+
+* add support for activating nvme-oF devices at boot automatically via kernel
+ cmdline, and maybe even support a syntax such as
+ root=nvme:<trtype>:<traddr>:<trsvcid>:<nqn>:<partition> to boot directly from
+ nvme-oF
+
* add a new systemd-project@.service that is very similar to user@.service but
uses DynamicUser=1 and no PAMName= to invoke an unprivileged somewhat
light-weight service manager. Use HOME=/var/lib/systemd/projects/%i as home
