I think this could be surprising - because we would be hiding all
squashfs filesystems from df, not just snapd ones. I think it would be
cleaner to consider that users don't generally want to see squashfs
stuff in df output by default anyway, and so hide it Ubuntu-wide.
I'm less sure about tmpfs. I can think of occasions where I have wanted
to see tmpfs usage (since it can run out, and has run out on me before).
But that's perhaps too much of a specialist case, and so I think it's
also OK to hide tmpfs by default from df on Ubuntu.
