Question about output from 'df'.



Hi,

In fstab on a Debian Testing machine I have the following:

# /dev/sda5
UUID=fbcdccf4-f329-4656-8ac2-7cff4c158404 /boot ext4
rw,errors=remount-ro 0 0
# /dev/sda6
UUID=37de7813-0f65-41dd-b4ae-55912e454d0f / ext4
rw,errors=remount-ro 0 1
# /dev/sda7
UUID=4f2719cd-5e8b-4440-85d9-80db2a7e528a /home ext4
rw,errors=remount-ro 0 0
# /dev/sda8
UUID=38d6809f-8c95-43c8-9a22-23fa1cbecdd4 swap swap sw 0 0

When I do 'df' (or look in System Monitor) I see the following for file 
systems:

/dev/disk/by-uuid/37de7813-0f65-41dd-b4ae-55912e454d0f 10896648 5101224
5235248 50% / 
/dev/sda5 769760 44844 684980 7% /boot 
/dev/sda7 599139368 344433792 224264420 61% /home

The output of 'blkid' is:
/dev/sda8: UUID="38d6809f-8c95-43c8-9a22-23fa1cbecdd4" TYPE="swap" 
/dev/sda5: UUID="fbcdccf4-f329-4656-8ac2-7cff4c158404" TYPE="ext4" 
/dev/sda6: UUID="37de7813-0f65-41dd-b4ae-55912e454d0f" TYPE="ext4" 
/dev/sda7: UUID="4f2719cd-5e8b-4440-85d9-80db2a7e528a" TYPE="ext4" 

Why is /dev/sda6 indicated as 'dev/disk/by-uuid' and the other two simply as /dev/sda5 and /dev/sda7? I can not remember that there has been a difference between the three in the df output before.
