Ok, i think i have something (didn't test it yet):
---------------------------------------------------------------
First i'd just get the normal contraint and use it to set the geom of
the partition in question:

constraint = ped_constraint_any( device );
ped_disk_set_partition_geom ( disk, c_partition, constraint, start,
end ) ;

now c_partition ->geom ->end contains a sector which lies nicely on a
cylinder boundary.

Next i'll set c_partition ->geom ->start to the value of the original
partition:

ped_geometry_set_start (c_partition ->geom, orig_start) ;

Then i'll get the exact contraint and set the final size of the
partition with this constraint:

constraint = ped_constraint_exact ( c_partition ->geom ) ;
ped_disk_set_partition_geom ( disk, c_partition, constraint, start,
end ) ;
-----------------------------------------------------------------

It's a bit hackish, but afaics it'll keep the startsector intact and the
end is nicely rounded on a cylinder boundary. Hopefully there's a better
way of achieving this, so keep them coming... :-)

Thanks,

Bart
