Y'know, Mark, this might be a reason for my continued makefile

For the things that I do, I typically have dependency trees that are
much deeper than 1.  For instance, the makefile we're currently using
to drive the installation and configuration of HACMP clusters has
depths in it as high as 8.  The histogram looks like:

targets depth
     59 1
     31 2
     12 3
      7 4
      3 5
      1 6
      2 7
      2 8

So while 50% of the targets are at a depth of 1, 23% of them are at a
depth of 3 or greater. 

I wonder where the difference in dependency usage is coming from?  Is
anyone else doing fully-automated cluster builds?  Something equally

(For the purposes of this discussion, "fully automated" means turn on
the power on a pair of bare machines, walk away, come back a couple
hours later and you've got an HA cluster.)
