[arch-general] Change UUID

[Guillermo Leira]

Hello!

I'm trying to change the UUID on a ext4 formatted partition of a virtual
machine disc. The machine is running under virtualbox, on Windows.

I'm using "tune2fs /dev/sda3 -U random", or "tune2fs /dev/sda3 -U UUID". I
have booted from the arch install disk, the partition is not mounted.

When I run this command, I only get this:

[root at archiso /]# ls /dev/disk/by-uuid/ -l
total 0
lrwxrwxrwx 1 root root 10 2009-03-12 14:27
323cc148-ff48-4038-a2e7-9908896a58fd -> ../../sda2
lrwxrwxrwx 1 root root 10 2009-03-12 14:27
36628cd2-0842-4be0-a631-12afbc48793d -> ../../sda3
lrwxrwxrwx 1 root root 10 2009-03-12 14:27
93f768dc-9161-4387-a83d-231da5f193ef -> ../../sda1
[root at archiso /]# tune2fs /dev/sda3 -U 00f46b25-8c12-4254-8d45-13be848c3da1
tune2fs 1.41.4 (27-Jan-2009)
[root at archiso /]# ls /dev/disk/by-uuid/ -l
total 0
lrwxrwxrwx 1 root root 10 2009-03-12 14:27
323cc148-ff48-4038-a2e7-9908896a58fd -> ../../sda2
lrwxrwxrwx 1 root root 10 2009-03-12 14:27
36628cd2-0842-4be0-a631-12afbc48793d -> ../../sda3
lrwxrwxrwx 1 root root 10 2009-03-12 14:27
93f768dc-9161-4387-a83d-231da5f193ef -> ../../sda1
[root at archiso /]#

Tune2fs does not give any error, but the UUID does not change.

Any ideas?
