I read the thread that lead to your change, it seemed reasonable to me.

I was trying to get a bit more of a feel for what was happening before
raising a PR.

No, /var is a partition on the single HD. There is a tmpfs on /var/shm
and one on /tmp.

The machine that hangs isn't running X11 but it is running a
postgresql server which creates a couple of files in /tmp.
