Perhaps I need to clarify a bit. Under none of the five-or-so install
options, did it recognise any of the partitions within vg_pigeon;
under the options that kept the volume group vg_pigeon, it suggested 3 new
partitions for /, /home and swap, none of which were the same size as the
original partitions, and *didn't* give the option of skipping formatting.

So at no point was a I presented with a /home patititon that matched the
alignment of the existing partition, and where I could unselect 'format'.
