regular user can destroy disk label?!?

[Harald Schmalzbauer]

Hello,

accidentally I did 'bsdlabel -w ar0s2' as unprivileged user but it was 
successfull.
Is this only possible because there was no mounted filesystem on it?
But I can imagine having data on unmounted filesystems.
Is it intended that regular useres can overwrite the label?
That's a big fault in my opinion.

Best regards,

-Harry
