I would simply sudo cp -r everything.

Oops, sudo cp -pr

Typo fix:

-xattrs -hard-links -acls

Should be of course: --xattrs --hard-links --acls Regards, mearon -- Merlin Büge

Also cp -pr does not preserve links or xattrs for example. Maybe cp -ar would be more appropriate.

Ok, actually I regularly backup to a tar archive and at least links are preserved. I seemingly missed to use the --xattrs switch, fortunately this never caused an issue for me, but I consider to add it to my scripts soon.

Thank you for the pointer and my apologies for the false advice.

you could simply

sudo systemd-nspawn -bqD /mnt/

from the existing install and run the commands required for your bootloader of choice, assuming this grub auto thingy does generate UUID based entries and your fstab (if you still should use fstab at all) does contain those, too, since sdx would change from x=b to x=a, if you remove the old drive.

Did I misunderstand something? Sure, if not both drives should be connected, you need a live media to install grub. My apologies.
