NAME

       systemd-fstab-generator - Unit generator for /etc/fstab

SYNOPSIS

       /lib/systemd/system-generators/systemd-fstab-generator

DESCRIPTION

       systemd-fstab-generator is a generator that translates /etc/fstab (see fstab(5) 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.

       The passno 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.

       See systemd.mount(5) and systemd.swap(5) for more information about special /etc/fstab
       mount options this generator understands.

       systemd-fstab-generator implements systemd.generator(7).

KERNEL COMMAND LINE

       systemd-fstab-generator understands the following kernel command line parameters:

       fstab=, rd.fstab=
           Takes a boolean argument. Defaults to "yes". If "no", causes the generator to ignore
           any mounts or swaps configured in /etc/fstab.  rd.fstab= is honored only by initial
           RAM disk (initrd) while fstab= is honored by both the main system and the initrd.

       root=
           Takes the root filesystem to mount in the initrd.  root= is honored by the initrd.

       rootfstype=
           Takes the root filesystem type that will be passed to the mount command.  rootfstype=
           is honored by the initrd.

       rootflags=
           Takes the root filesystem mount options to use.  rootflags= is honored by the initrd.

       mount.usr=
           Takes the /usr filesystem to be mounted by the initrd. If mount.usrfstype= or
           mount.usrflags= is set, then mount.usr= will default to the value set in root=.

           Otherwise, this parameter defaults to the /usr entry found in /etc/fstab on the root
           filesystem.

           mount.usr= is honored by the initrd.

       mount.usrfstype=
           Takes the /usr filesystem type that will be passed to the mount command. If mount.usr=
           or mount.usrflags= is set, then mount.usrfstype= will default to the value set in
           rootfstype=.

           Otherwise, this value will be read from the /usr entry in /etc/fstab on the root
           filesystem.

           mount.usrfstype= is honored by the initrd.

       mount.usrflags=
           Takes the /usr filesystem mount options to use. If mount.usr= or mount.usrfstype= is
           set, then mount.usrflags= will default to the value set in rootflags=.

           Otherwise, this value will be read from the /usr entry in /etc/fstab on the root
           filesystem.

           mount.usrflags= is honored by the initrd.
