1004 * 1. Background: we can't do name lookups (NSS) from PID 1, since it might involve IPC and thus activation,
1005 * and we might hence deadlock on ourselves. Hence we do all user/group lookups asynchronously from the forked
1006 * off processes right before executing the binaries to start. In order to be able to clean up any IPC objects
1007 * created by a unit (see RemoveIPC=) we need to know in PID 1 the used UID/GID of the executed processes,
1008 * hence we establish this communication channel so that forked off processes can pass their UID/GID
1009 * information back to PID 1. The forked off processes send their resolved UID/GID to PID 1 in a simple
1010 * datagram, along with their unit name, so that we can share one communication socket pair among all units for
1011 * this purpose.
1012 *
1013 * You might wonder why we need a communication channel for this that is independent of the usual notification
1014 * socket scheme (i.e. $NOTIFY_SOCKET). The primary difference is about trust: data sent via the $NOTIFY_SOCKET
1015 * channel is only accepted if it originates from the right unit and if reception was enabled for it. The user
1016 * lookup socket OTOH is only accessible by PID 1 and its children until they exec(), and always available.
1017 *
1018 * Note that this function is called under two circumstances: when we first initialize (in which case we
1019 * allocate both the socket pair and the event source to listen on it), and when we deserialize after a reload
1020 * (in which case the socket pair already exists but we still need to allocate the event source for it). */
