+    <title>Description</title>
+
+    <para><filename>systemd-debug-generator</filename> is a generator
+    that reads the kernel command line and understands three
+    options:</para>
+
+    <para>If the <option>systemd.mask=</option> or <option>rd.systemd.mask=</option>
+    option is specified and followed by a unit name, this unit is
+    masked for the runtime (i.e. for this session — from boot to shutdown), similarly to the effect of
+    <citerefentry><refentrytitle>systemctl</refentrytitle><manvolnum>1</manvolnum></citerefentry>'s
+    <command>mask</command> command. This is useful to boot with
+    certain units removed from the initial boot transaction for
+    debugging system startup. May be specified more than once.
+    <option>rd.systemd.mask=</option> is honored only by initial
+    RAM disk (initrd) while <option>systemd.mask=</option> is
+    honored only in the main system.</para>
+
+    <para>If the <option>systemd.wants=</option> or
+    <option>rd.systemd.wants=</option> option is specified
+    and followed by a unit name, a start job for this unit is added to
+    the initial transaction. This is useful to start one or more
+    additional units at boot. May be specified more than once.
+    <option>rd.systemd.wants=</option> is honored only by initial
+    RAM disk (initrd) while <option>systemd.wants=</option> is
+    honored only in the main system.</para>
+
+    <para>If the <option>systemd.debug_shell</option> or
+    <option>rd.systemd.debug_shell</option> option is
+    specified, the debug shell service
+    <literal>debug-shell.service</literal> is pulled into the boot
+    transaction and a debug shell will be spawned during early boot.
+    By default, <filename>&DEBUGTTY;</filename> is used, but a specific tty can also be set,
+    either with or without the <filename>/dev/</filename> prefix.
+    Note that the shell may also be turned on persistently by enabling it with
+    <citerefentry><refentrytitle>systemctl</refentrytitle><manvolnum>1</manvolnum></citerefentry>'s
+    <command>enable</command> command.
+    <option>rd.systemd.debug_shell=</option> is honored only by initial
+    RAM disk (initrd) while <option>systemd.debug_shell</option> is
+    honored only in the main system.</para>
+
+    <para><filename>systemd-debug-generator</filename> implements
+    <citerefentry><refentrytitle>systemd.generator</refentrytitle><manvolnum>7</manvolnum></citerefentry>.</para>
