Does the data in an ext4 filesystem refer to absolute positions on the disk, or is it all relative to the start of the specific partition?
I want to know this because I want to move an ext4 filesystem so that it starts earlier on the disk. My current ext4 partition starts somewhere in the middle of the disk and extends to the end, and the only way to grow this filesystem is to make it start earlier.
So, can I move the ext4 filesystem around with dd, and expect it to work at its new address?
Of course, I would also have to edit my partition table, but that is a separate concern :)

. Nevertheless, I would like to know whether or not it could have worked with moving the filesystem withdd
