Have a look at /etc/init.d/mountoverflowtmp.

Your root filesystem is full.  This triggers the mounting of a
tmpfs on /tmp *irrespective* of the RAMTMP option, in order to
allow you to log in.

Solution: free up some space on your root filesystem, and all
will return to normal.  Mounting a filesystem on /tmp would have
solved this specific problem by making more than a megabyte of
free space available, which would avoid triggering this condition.
