| <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 <varname>passno</varname> field is treated |
| like a simple boolean, and the ordering information is |
| discarded. However, if the root file system is |
| checked, it is checked before all the other |
| file systems.</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> |
