Sorry to bother once again, but while evaluating the tags on this question I came up with another one:
- partition
- partitioning
- partition-scheme (Doesn't need a separate tag imo)
- disk-partition (Partition(ing) is used for this already)
- partitioning-software (Partitioning is not hardware, so software is likely inherent)
All those tags can be housed in either partition or partitioning (I prefer the second one, it's action-wise)
