True, provided the source and destination are the partitions covering the entire physical disk. B) It will get the boot and > partition records, right?

Mostly consistency problems, such as corrupted/truncated files if the source disk changes while being copied to the destination. Same reason you don't DDR a pack with active page/spool on it and expect it to be a completely clean copy. Most of this sort of inconsistency is fixable with fsck, but if you want to guarantee a clean copy, then you can't be changing the disk out from under dd. -- db
