Okay, thanks, will do next time.

Actually there is no particular reason -- I stumbled upon this possible
configuration just out of curiosity: I did see that RAMLOCK=no and
RAMSHM=no settings in /etc/default/tmpfs allow one to use /run/lock and
/run/shm under the same /run filesystem, and deciced to check if the
similar trick would work for /tmp.

As documented in /usr/share/doc/initscripts/README.Debian an (initially
broken at the very beginning of startup) symlink from /tmp to /run/tmp
would do the trick, but it didn't -- there you go.
