I have only briefly looked at this document, but I couldn't quite figure out whether all you need is to enforce that the first partition starts at sector number 64 *in any case* and you don't care about other partitions or do you need alignment according to disk geometry? Current setup-storage in mainline FAI still does use cylinder-aligned partitions, but this requirement has been dropped in the experimental branch. I'd see several options for the future: - Drop any kind of alignment and let people create a dummy-partition such that the effective data partition only starts as of the 64th sector. - Make alignment configurable. But then the kind of alignment must get clarified. Best, Michael
