You may find this element of my preseeding framework useful: https://hands.com/d-i/preseed/classes/partition/_/unfilled/ which is the bit of a recipe, and the preseed & late script bits, to create and then remove such a partition. Cheers, Phil. P.S. The rest of the framework is probably overkill if you have already got your preseed script done, but it's got quite a lot of examples hidden in there that may be of interest: https://hands.com/d-i BTW If you're wondering how the above "_/unfilled" bit gets used, one can specify it as a dependency, usually in partition classes, thus: https://hands.com/d-i/classes/partition/multi/spare/filter which means that if one specifies e.g. `partition/multi/spare` as a class that you're using for the install, and you'll get a multi partition layout with a spare bit.
