I had some discussion with Steve Langasek, one of debian's release manager,
about including parted 1.6.12 in sarge. Since parted is ipart of base, and has
thus been frozen since more or less amonth, this cause problem, and we were
wondering if your fix could not be backported.

Steve (vorlon on irc) suggested : 

  08:45 < vorlon> svenl: it looks to me like the parted bug could be
  backported w/o ABI breakage by hiding the new geom info in the arch_specific

I have some reservation, given that libparted really has no concept of hidden
data structures, and mostly exports everything, but i suppose that the two new
geom stuff could be added at the end of the structure and still keep backward
compatibility. Not sure though.

Do you have any insight on this question ?
