[Parted-maintainers] Bug#392767: Fixed RC bug in frozen parted : #392767: [mac] parted is unable to reread partition tables created by d-i/partman.

[Robert Millan]

I'm sorry.  Please feel free to disable the patch; I'm thinking it was not a
good idea to apply it in the package before it was merged upstream (as it was
about to, last time I visited this).

Apologises for the hassle.
