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. + +* 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=?
