--- Comment #1 from Petr Uzel <puzel@xxxxxxxx> 2012-04-01 10:01:40 UTC ---
I tried to reproduce. It is true that sfdisk spits out an ERROR
about missing msdos signature, but creates the partition table and 
partition entry anyways (see the transcript below).

Could you please be more specific on what exactly is the problem
in your case?  Thanks in advance.
