rc.S scripts have always had the capability of setting environment
variables. We have to be *very* careful here before such a change is
made. This means auditing *ALL* rcS scripts in Debian to know which ones
need this capability, and what it is used for.
We will get enough of a speedup by runining runlevel 2 in parallel, even if
parts of rcS have to be serialized.
