Re /var/, that may hold more than just logs, depending on your usage.
For me, /var/lib/docker/ tends to hold several 10s of GB, changes a lot
and is not something I'd like to have in the same filesystem. If you're
tracking testing and/or ceres, your /var/cache/apt/ may end up having a
few GB of packages and metadata if you don't `apt clean` regularly (or
set up APT::Periodic to manage things for you).

As for /tmp, yes, the default has been to use tmpfs for that for quite a
while now, but one might still have this on disk. In that case, I would
consider switching to tmpfs *unless* you're on a very memory constrained
system.

# For clarity, when you're using tmpfs for /tmp means you are "mounting"
# it separately. Without a separate mount, it lives in the same place
# as your / filesystem.

Hope this helps,
