Yeah. I know.

Did you read my entire email or just the part where i tried specifying a
sector outside the extended partition?
The example was just to illustrate that it is impossible to (re)create a
partition layout that has been created by the Ubuntu installer.

Still 'sfdisk' complains about "Warning: extended partition does not
start at a cylinder boundary." 

The problem is there's something wrong with the partition layout created
by the Ubuntu installer.
