Wow!

Yes I wasn’t sure if keeping links could not break something. But I
guess it shouldn’t harm since after mounting everything will have the
same place on the filesystem.
I agree that rsync -aHAX seems a much better option. I would have
resorted to that if things kept breaking with cp. That’s what I meant by
"just using cp is a bit brutal". I wasn’t sure which of
the uncountable options of rsync to use though ^^
