55 | <para><filename>systemd-fstab-generator</filename> is a generator | |
56 | that translates <filename>/etc/fstab</filename> (see | |

58 | for details) into native systemd units early at boot and when |
59 | configuration of the system manager is reloaded. This will | |
60 | instantiate mount and swap units as necessary.</para> | |
61 | ||
62 | <para>The <varname>passno</varname> field is treated like a simple | |
63 | boolean, and the ordering information is discarded. However, if | |
64 | the root file system is checked, it is checked before all the | |
65 | other file systems.</para> | |
