How to make a clone on the same system with tar?
I have already tried this and it is not working. I took a tar of my root directory and read it into another like-sized partition on the same machine.
I modified the fstab on the clone so that / points to itself, but when I ask Grub to go there, it instead ends up in the original partition. This is a problem because now the original partition is broken in some other way, so I do not have what I need.
Grub, by the way, was installed from yet a third bootable partition that is running a fresh install of 18.04.1. The clones are 16.04.5.
I verified that things are as I described by taking a copy (with dd) of the original (onto a large attached USB drive), then zeroing out the first 8 MB. I had the 18.04.1 update grub, and that partition no longer appeared. However, attempting to boot the clone took a long time and ended in busybox (in other words total failure).
I copied 8 MB back and I'm back to where I was.
So how do I do fix this and do it right in the future?

I haven't been able to try it, but it's possible that question [askubuntu.com/questions/400210] contains my answer.
