+* When runlevel3.target is used to define dependencies on other units,
+ then we don't pick it up currently, since nothing ever references
+ runlevel3.target, and never figure out it actually is just an alias
+ for multi-user.target. A hackish fix could be to add a .wants link
+ from multi-user.target to runlevel3.target, if it is a symlink to
+ it. Best would be to create this .wants/ symlink from
+ sysv-generator. systemd would then load the referenced unit, figure
+ out it is just an alias and that the dependency would be on itself
+ and suppress it. Thus the alias and its deps would be loaded as
+ desired.
+
+* PID 1: when invoking systemctl preset-all on first boots, operate in
+ an exclusively additive way, i.e. never remove any pre-existing
+ symlinks, only add new ones.
+
+* 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.
