关于fstab中LABEL=/
 在fstab中看到LABEL=/ 最此不解，经查看资料 这个是磁盘的卷标方便记录

只用命令可以看到分区的UUID和卷标，在fstab中经常看到UUID做标识的挂载点，也会看到LABEL=/ 卷标的挂载。
[root@localhost ~]# blkid
/dev/sda1: UUID="b7e06715-4634-4a33-8109-42cc96564f7b" TYPE="ext4"
/dev/sda2: UUID="RodAAP-XHJC-mV6r-KLwW-i31Q-ND7q-QW12q5" TYPE="LVM2_member"
/dev/mapper/VolGroup-lv_root: UUID="99973688-b2ca-4da9-a1b7-d6103853e25d" TYPE="ext4" LABEL="/"
/dev/mapper/VolGroup-lv_swap: UUID="1339776b-28a9-4f7f-ba5b-5e8cef81c83c" TYPE="swap"
/dev/sdb1: UUID="WYRYIi-YOWs-HO1A-Cr5S-BDuH-wAGc-AveLYY" TYPE="LVM2_member"

[root@localhost ~]# e2label /dev/sda1 boot

这样就行了，修改/etc/fstab
#
# /etc/fstab
# Created by anaconda on Mon Dec  5 21:45:07 2011
#
# Accessible filesystems, by reference, are maintained under '/dev/disk'
# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info
#
LABEL=/ / ext4    defaults        1 1
LABEL=boot /boot                   ext4    defaults        1 2
/dev/mapper/VolGroup-lv_swap swap                    swap    defaults        0 0
tmpfs /dev/shm                tmpfs   defaults        0 0
devpts /dev/pts                devpts  gid=5,mode=620  0 0
sysfs /sys                    sysfs   defaults        0 0
proc /proc                   proc    defaults        0 0

这样是不是很方便记录。
