LABEL e UUID

Blkid de uso básico

1. Ver LABEL

# blkid -s LABEL
/dev/hda3: LABEL="/"
/dev/hda1: LABEL="/boot1"

2. Exibir UUID

# blkid -s UUID
/dev/hda3: UUID="440612e0-9cea-4751-8e59-07ebffc589c2"
/dev/hda1: UUID="027ecc62-d346-411d-ae6c-c3eaa87fb195"

3. Alterar nome do LABEL

e2label O novo rótulo do dispositivo, por exemplo, / dev / hda1 é nomeado / boot:

e2label /dev/hda1 /boot

4. Use LABEL / UUID no comando mount

mount LABEL=/boot1 /boot
mount UUID="51f7e9a4-5154-4e29-a7a6-208417290b85" /mnt/

5. Use LABEL / UUID no / etc / fstab

/etc/fstab
LABEL=/                                        /        ext3    defaults   1   1
LABEL=/boot1                                   /boot    ext3    defaults   1   2
UUID＝"e61f4197-5f00-4f4f-917c-290922a85339"   /usr     ext3    defaults   1   12
