Why would it fail back to serial?  It's already too late.  For example, 
if networking "fails", a lot things that depend on it will actually 
still run (well, if you've got localhost working and stuff.)

You create dependencies like "yeah, this one needs network" and stuff 
like that, and it will boot in order from there.  

You ever play with Lattice Graphs in school?  Lines can be traced to be 
run in parallel, and others will run serial.  Shoot, we could call all 
these daemons "packages" and run it through RPM's topological sort! :)

take care,
