sfdisk has "dump" mode, and it can also import old dump to new disk.
That dump mode doesn't help if the partition table is currently munged, and sfdisk is extraordinarily unforgiving of the tiniest mistake in human-generated input.
But it seems I could generate correct input for sfdisk from the entries in /proc/partitions ?
But I notice "man sfdisk" has a warning against use with large partitions, which it defines as > 8GB. Hopefully this no longer applies?
