Features:
+* Introduce $LISTEN_NAMES to complement $LISTEN_FDS, containing a
+ colon separated list of identifiers for the fds passed.
+
+* networkd: implement BindCarrier= logic to .network units that binds
+ application of the file to the carrier sense on another interface,
+ in order to implement uplink/downlink logic.
+
+* make networkd subscribe to PrepareForSleep(false) and refresh all
+ DHCP leases then.
+
+* when the fstab-generator runs in the initrd, it should create a /dev/null mask for systemd-fsck-root.service, to avoid that the the root fs is fsck'ed twice.
+
+* maybe introduce WantsMountsFor=? Usecase:
+ http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
+
* rework kexec logic to use new kexec_file_load() syscall, so that we
don't have to call kexec tool anymore.
