I'm trying to update my current source tree but this 
fails. I'm in /usr/src and do a "cvs update -dP".
It seems to run fine but then stops with:

cvs server: Updating distrib/notes/arm32
cvs server: Updating distrib/notes/atari
cvs server: Updating distrib/notes/common
cvs [server aborted]: unable to parse
/cvsroot/basesrc/distrib/notes/common/main,v; `auth
or' not in the expected place

I use anoncvs@sunsite.univie.ac.at as CVS server via ssh. This is my
first approach to build NetBSD from source and I'm not experienced
with CVS so maybe I did some stupid things during setup the source
tree. But I was able to checkout, update and compile the i386 kernel
sources including the i386mp branch so I think I'm not totally wrong :)
Further questions that came up during this:

- What is the best way to "clean" up the source tree? Deleting
  everything and reinstalling is not much fun.

- The recommended way to setup the source tree for the first time
  is to download the source-tarfiles of a recent snapshot and the
  do a cvs update. But by doing this I would have "cvs.netbsd.org"
  in all my CVS/Root files which is probably not what I want. Is
  is possible to just overwrite all CVS/Root files with a new one
  which contains a different cvs server before doing the update?

- is it possible to checkout/update the kernel sources for selected
  architectures only? At the moment, I get all architectures but I
  only need alpha,i386 and sparc. This seems to be a big overhead 
  to me.
