I'm not sure how my /tmp directory works. But I've noticed a couple of times I
run out of space on it.

Why is my mount reporting it's 10M? That's tiny. I'm sure I didn't purposefully
set that whilst installing Debian.

Why does df -h give two entries for tmpfs, where both don't seem to be fully
used!
