<title>Description</title>
<para><filename>systemd-fstab-generator</filename> is
a generator that translates
<filename>/etc/fstab</filename> (see
<citerefentry><refentrytitle>fstab</refentrytitle><manvolnum>5</manvolnum></citerefentry>
for details) into native systemd units early at boot
and when configuration of the system manager is
reloaded. This will instantiate mount and swap units
as necessary.</para>
<para>The <term><varname>passno</varname></term> field
is treated like a simlpe boolean, and the ordering information
is discarded. However, the root filesystem is checked
before all the other filesystems.</para>
<para>See
<citerefentry><refentrytitle>systemd.mount</refentrytitle><manvolnum>5</manvolnum></citerefentry>
and
<citerefentry><refentrytitle>systemd.swap</refentrytitle><manvolnum>5</manvolnum></citerefentry>
for more information about special
<filename>/etc/fstab</filename> mount options this
generator understands.</para>
<para><filename>systemd-fstab-generator</filename>
implements the <ulink
url="http://www.freedesktop.org/wiki/Software/systemd/Generators">generator
specification</ulink>.</para>

<title>Kernel Command Line</title>
<para><filename>systemd-fstab-generator</filename> understands
the following kernel command line parameters:</para>
<variablelist class='kernel-commandline-options'>
<varlistentry>
<term><varname>fstab=</varname></term>
<term><varname>rd.fstab=</varname></term>
<listitem><para>Takes a boolean
argument. Defaults to
<literal>yes</literal>. If
<literal>no</literal>, causes the
generator to ignore any mounts or swaps
configured in
<filename>/etc/fstab</filename>. <varname>rd.fstab=</varname>
is honored only by initial RAM disk
(initrd) while
<varname>fstab=</varname> is
honored by both the main system and
the initrd. </para></listitem>
