Create LABEL for filesystems in Linux

LABEL is used in /etc/fstab and system boot, such as cmdline.txt and grub, to allow the mounting identify the filesystem..

In order to allow system recognize the LABEL, blkid needs to show the filesystem has the LABEL.

Assign LABEL during filesystem creation

mkfs.vfat -n "label" /dev/XXX

mkfs.ext4 -L "label" /dev/XXX

mkfs.btrfs -L "label" /dev/XXX

LABEL can be changed after filesystem created.

e2label /dev/XXX "new label" using e2fsprogs

btrfs filesystem label /dev/XXX "new label" using btrfs-progs

reiserfstune -l "new label" /dev/XXX using reiserfsprogs

jfs_tune -L "new label" /dev/XXX using jfsutils

xfs_admin -L "new label" /dev/XXX using xfsprogs

fatlabel /dev/XXX "new label" using dosfstools
mlabel -i /dev/XXX ::"new label" using mtools
