Comment 75 for bug 571038

The following should be step 2.5 (i.e. between 2. and 3.)

dd if=/dev/sdb1 of=/dev/sdb1 seek=446 skip=462 count=16 bs=1
dd if=/dev/zero of=/dev/sdb1 seek=462 count=16 bs=1

Explanation:

It turned out that though sfdisk recognized an attempt to write 0-sized partition, it still writes correct entry in EBR. To alleviate that I simply move second entry on place of first one and fill second entry with zeros. It triggers udisks into thinking it was the last one.
