+@cindex entry point, for Docker images
+@item --entry-point=@var{command}
+Use @var{command} as the @dfn{entry point} of the resulting pack, if the pack
+format supports it---currently @code{docker} and @code{squashfs} (Singularity)
+support it.  @var{command} must be relative to the profile contained in the
+pack.
+
+The entry point specifies the command that tools like @code{docker run} or
+@code{singularity run} automatically start by default.  For example, you can
+do:
+
+@example
+guix pack -f docker --entry-point=bin/guile guile
+@end example
+
+The resulting pack can easily be loaded and @code{docker run} with no extra
+arguments will spawn @code{bin/guile}:
+
+@example
+docker load -i pack.tar.gz
+docker run @var{image-id}

+
+The @code{(gnu services auditd)} module provides the following service.
+
+@defvr {Scheme Variable} auditd-service-type
+
+This is the type of the service that runs
+@url{https://people.redhat.com/sgrubb/audit/,auditd},
+a daemon that tracks security-relevant information on your system.
+
+Examples of things that can be tracked:
+
+@enumerate
+@item
+File accesses
+@item
+System calls
+@item
+Invoked commands
+@item
+Failed login attempts
+@item
+Firewall filtering
+@item
+Network access
+@end enumerate
+
+@command{auditctl} from the @code{audit} package can be used in order
+to add or remove events to be tracked (until the next reboot).
+In order to permanently track events, put the command line arguments
+of auditctl into @file{/etc/audit/audit.rules}.
+@command{aureport} from the @code{audit} package can be used in order
+to view a report of all recorded events.
+The audit daemon usually logs into the directory @file{/var/log/audit}.

+service is the Singularity package to use.
