Hmmm.... I indicated this some time ago and got some grief over this. 
Few of the distro makers seem to like this concept.  I want the unit up, 
running all drivers needed (and only those drivers needed), with the 
network, and a barebones admin package (ssh, ipmitools, ...).  Getting 
there with most prebuilt distros is excruciatingly hard.

I have gotten SuSE down to a 1.4 GB install, bare minimum that I can 
make it and satisfy all dependencies, and have a functional compute 
node.  More if I need to get the 32 bit packages there.

RH I have not seen an install below about 2GB.  Rocks tries to do a 
minimal install, and yet you see packages that largely won't be used on 
nodes being installed in order to satisfy dependencies of packages that 
will be used.  This is not the Rocks people's fault, it is the 
underlying distribution.

You can use DSL and other "small" distros as long as you don't mind 
using ancient kernels, missing drivers, ...  This unfortunately doesn't 
satisfy the needs.  Caos3 should (in theory, haven't tried it yet) 
handle most of this, be a very tight install, limited package dependency 
radius, and still be quite usable/fast.

YES!!!!!

These problems plague every RH derived distro as well.  FC derived as 
well.  Anaconda may be great at many things.  Robustly installing 
software and configuring systems is not one of them.
