systemd-fstab-generator(8)



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.
