genfstab

Generate output suitable for addition to the /etc/fstab file. More information: https://manned.org/genfstab.

• Generate the /etc/fstab file using volume UUIDs during an Arch Linux installation (requires root permissions):

genfstab -U {{/mnt}} >> {{/mnt/etc/fstab}}

• Display fstab-compatible output based on volume labels:

genfstab -L {{path/to/mount_point}}

• Display fstab-compatible output based on volume UUIDs:

genfstab -U {{path/to/mount_point}}

• Display fstab-compatible output based on the specified identifier:

genfstab -t {{LABEL|UUID|PARTLABEL|PARTUUID}}

• Append a volume into the /etc/fstab file to mount it automatically:

genfstab -U {{path/to/mount_point}} | sudo tee -a /etc/fstab
