Make /var/tmp a symbolic link to /tmp. The creation of /var/tmp in the

often space-constrained /var filesystem was a historical mistake.  There
are big implications for the daemons which assume they won't run out of
space, and this is a first step towards trying to improve the situation.
Move /tmp to the same 7-day expiration rules that /var/tmp had.
vi.recover works just as well as before, except on memory filesystems;
indicating that vi should be repaired to write files into homedirs or
something.
