that reads the kernel command line and understands three

options:</p><p>If the <code class="option">systemd.mask=</code> option is specified
|
|
and followed by a unit name, this unit is masked for the runtime,
|
|
similar to the effect of

|
<a href="systemctl.html"><span class="citerefentry"><span class="refentrytitle">systemctl</span>(1)</span></a>'s
|
|
<span class="command"><strong>mask</strong></span> 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.</p><p>If the <code class="option">systemd.wants=</code> 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.</p><p>If the <code class="option">systemd.debug-shell</code> option is
|
|
specified, the debug shell service
|
|
"<code class="literal">debug-shell.service</code>" is pulled into the boot
|
|
transaction. It will spawn a debug shell on tty9 during early
|
|
system startup. Note that the shell may also be turned on
|
|
persistently by enabling it with
|
|
