Well, the question is how we should adjust logical partition in that case ?
Also, there might be unresizable partitions, or partitions with FS not
supported for a particular operation in Parted, so this really is a non
trivial issue !

I guess it depends on the file system.

?? I don't understand clearly...
If you're are talking about a generic block by block move, this is not
compatible with a non destructive operation in case of complete interruption
in the middle of the process.
