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.
