Description of problem:
Anaconda allows you to set the size of a partition. Later on, on the installed system, if you check the partitioning with "fdisk", fdisk warns that the partitions do not start/end on a partition boundary.
This may or may not be a problem. Would an option to align partitions on cyclinder boundaries be useful? Is fdisk too eager in warning??
anaconda will follow any special aligning the kernel informs us about. However, I doubt what you're seeing in fdisk causes any problems. At least, we've been doing this for a couple releases now and I have yet to hear of anything beyond the obvious cosmetic problem.
