Personally, I'd be very interested to know how you did this 'from
scratch'.

I myself have done this from the post-bootstrap (but pre emerge system)
stage on, but I cant bootstrap with 3.0.x, why?

Well, the image the ISO installs has many applications on it, not linked
statically (eg. tar, etc) -- compiling gcc3.0.4 works fine, but as soon
as it then compiles glibc 2.2.5 and installs it, nothing else works.

The utilities on the install image look for glibc 2.2.5 compiled with
gcc 2.95.x.  So until there is an install image that has statically
linked binaries on it, I dont see how a bootstrap can be achieved using
3.0.x compilers.

I too, however, have installed a 3.0.x based system.  I did the
bootstrap on 2.95.3, then first thing after bootstrap, I merged gcc
3.0.4, and then did my emerge system.  As Geert said, a few problems
along the way, but not many.  I too made patches for all the problems I
found, I submitted them to Geert.  The patches I made are ALL backward
compatable to 2.95.3 (I believe, I've not tested this).  But then, I
could also have compiled a different package set than he did.
