SYSTEMD-FSTAB-GENERATOR(8) systemd-fstab-generator SYSTEMD-FSTAB-GENERATOR(8)
NAME
systemd-fstab-generator - Unit generator for /etc/fstab
SYNOPSIS
/usr/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.usrflages= 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.
