If it hasn't been changed lately, disklabel can use the same kind of love, for the cases where it rounds the size down to zero by itself. It's been on my todo for some time. Be warned; disklabel has special needs, so it may or may not be trivial to cook a nice diff for it. e.g. # disklabel sd0 Label editor (enter '?' for help at any prompt) > a partition: [j] offset: [73256400] size: [16] FS type: [4.2BSD] > w > q No label changes. # disklabel sd0 /.../ disklabel: warning, partition j: size 0, but offset 73256416 /Alexander
