+This is the service repository for services that should be started
+early, typically before the network goes up.
+"klogd" and "syslogd" services should be present as soon as possible,
+because other services might need them. However, since they need
+a writable disk filesystem, they can't be run as early as a getty.

+This syslogd emulation works on any Unix where syslog() is
+implemented via a connection on the /dev/log Unix-domain socket.
+It needs a Unix superserver (see s6-networking, ucspi-unix or
+ucspi-ipc) and ucspilogd.
+A ucspilogd process is spawned for every syslog() client. It
+processes logs and sends them to stderr, i.e. the service's
+logger.
