[parted-devel] partition alignment...

For optimal filesystem performance (and best user experience) on
soft/hard RAID arrays, flash devices, SSDs etc, partitions need to be
aligned.

In absence of a reliable way to get information from the kernel, it
strikes me as being a safe way to align partitions to (eg) a 1MB
boundary (like in MS Windows 7 and Server 2008) by default for devices
> eg 512MB...certainly it may big step up from the 63-sector default
alignment on DOS disk labels.

There will be opportunity to add 'smarter' alignment when kernel
interfaces and vendors mature, but this will take time.

What objections are against this?

Thanks,
  Daniel
