Can I dd XFS home to backup drive then nuke home & resize root recreating new XFS home then dd file structure back?!?

Cannot upgrade Mint 17.3 to 18 as not enough room in root.

Would this work with a simple offline file manager copy?

  • for the XFS file system, you should use xfsdump and xfsrestore, and not dd

sudo apt-get clean

freed enough space on root for upgrade. I had 1.3GB jumping to 7GB when cache cleared.
