genfstab - Man Page

• Display an fstab compatible output based on a volume label: genfstab -L path/to/mount_point
• Display an fstab compatible output based on a volume UUID: genfstab -U path/to/mount_point
• A usual way to generate an fstab file, requires root permissions: genfstab -U /mnt >> /mnt/etc/fstab
• Append a volume into an fstab file to mount it automatically: genfstab -U path/to/mount_point | sudo tee -a /etc/fstab

genfstab [options] root

genfstab helps fill in an fstab file by autodetecting all the current mounts below a given mountpoint and printing them in fstab-compatible format to standard output. It can be used to persist a manually mounted filesystem hierarchy and is often used during the initial install and configuration of an OS.
