Hi,
I took a hard drive from a windows box, formatted in NTFS and plugged it 
  into my xUbuntu Intrepid.
I dont know what component autodetects the UUID (udev?), but it has 
created a /dev/disk/by-uuid/9050842050840EE2 (which is the UUID of the 
NTFS partition)
Then, I made a mkfs.ext3 on it and thus it has changed the UUID.
My UUID is know: 9f04af4c-2e18-4fea-868f-a68991483734
when editing fstab and mounting the partition:

   # mount /malalaka
   mount: special device
   /dev/disk/by-uuid/9f04af4c-2e18-4fea-868f-a68991483734 does not exist

Yes, there was no /dev/disk/by-uuid/9f04af4c-2e18-4fea-868f-a68991483734
And the /dev/disk/by-uuid/9050842050840EE2 was still there.

I had to make a:
   # rm /dev/disk/by-uuid/9050842050840EE2
   # invoke-rc.d udev restart
to have /dev/disk/by-uuid/9f04af4c-2e18-4fea-868f-a68991483734

Then mounting it was OK.
Bug? Just a side effect of udev automation?
I wont have to plug drives many times, so it's a use case specific 
problem. just want to share and know if it's a bug.
