df displays UUID rather than the device name

Several distros set up your boot device in grub using the UUID.  Unfortunately this can cause the output from the df command to display the long uuid (e.g. /dev/disk/by-uuid/0ebcf386-83eb-4639-b1ba-be73a7f60efc) rather than the device name (e.g. /dev/sda1)

To change this edit the file /etc/default/grub on Debian use the command

sudo vi /etc/default/grub

find the line which contains


If it has a # as the first character on the line this character should be deleted then save the file.

Now update the grub using the command

sudo update-grub

After you reboot the df command will display the device name.
