I do have /home on its own partition and I had thought of fetching a
dpkg -get-selections to help restore from a clean install.
I had not thought to back up and selectively recover /etc and /var.
I get backing up and comparing /etc now that I think about it. Although
/etc is holding configuration type information which I can't see a
reason it would change between 32 & 64 bit. So I would only really be
looking at recovering post install customisations to /etc. Is that correct?
However and this shows a gap in my knowledge, but what could be in /var
that is worth keeping? Apart from maybe logs.
Again thanks for your feedback.
