- * setup-storage/Sizes.pm: for backward compatibility with previous
- setup-storage versions, msdos partitions must be aligned to cylinder
- boundary and alignment constraints must not apply for start position of
- partitions 1 and 5. Preserving partitions on systems installed with previous
- versions of setup-storage breaks without this.

-
- * setup-storage/{Parser.pm,Sizes.pm}: Align partition sizes to sectors or
- user-requested alignment on all disk labels, dropping DOS
- cylinder-alignment. Thanks Patrick Cervicek for suggesting the
- user-specified alignment.
- * setup-storage.8: Document new align-at option.
- * setup-storage/Sizes.pm: Take alignment into account for partition size
- computation (thanks Frank Doepper for bringing up this problem). Size of
- extended (partition) boot record is 2 sectors.
- * setup-storage/Sizes.pm: Do not rely on bios_sectors_per_track information
- for computing the start location of first partition, always use 63 sectors
- gap. Thanks Mathieu Alorent for extensive testing.
