Did udev change behaviors at some point then?  I've been using an older
udev and didn't run into that problem.  I changed from /tmp to /dev/shm
since we don't know that /tmp is writable at that point so we were
instead getting errors there.  I wonder if we should just switch to
re-creating the contents for that step?
