The patch implements the following logic:

- always warn if disk have GPT

- in interactive mode: explicitly warn that any change to MBR will
 result in GPT removal, ask for confirmation, and remove GPT

- in non-interactive mode: remove GPT and explicitly note this fact

Wouldn't it be more reasonable to have a new command-line option to
remove the GPT?  In non-interactive mode without the new option, if the
GPT exists the command should fail with a non-zero exit status (and an
appropriate error message).

I basically want it to do the right thing for sysinst. As long as that
works automatically, I don't mind.

Shouldn't sysinst check for existence of the GPT and ask the user if it should really be removed? If the user says "Y" then sysinst can use the new option flag to force removal.

I just don't like doing irreversible damage without making certain that that is what the user intended. Yes, we can give the user enough rope to hang him/herself, but we don't necessarily need to have the hangman's noose already tied, ready to slip around the user's neck! :)
