Thanks for the fast internet in Chennai, downloading things were quite a smooth
experience. But unlike the 36 hours one-shot build I did in a NetBSD VirtualBox
instance, this was not easy. My aim was to cross-compile from a Windows 7 x64
environment to generate binaries for NetBSD-i386 environment.

Setting up Cygwin, NetBSD-CURRENT source tree and the right tools was not too
hard. I decided to run the compile in 3 parts

• Build the Tool Chain

  The tool chain build was the smooth one, took roughly couple of hours but was
  done without errors.

• Build the NetBSD Kernel

  The Kernel build took slightly longer but it got finished without issues.

• Build the Userland

  This is where I faced the issue, apparently some of the applications failed to
  compile and I do not remember exactly which ones, but I did not pursue this
  into detail, since the project I will be working on mainly involves the above
  two. But this is something I would like to look back into and resolve when I
  get time for it.

Of course the hunt is never complete without a kill or in this case the build is
never complete without actually being able to boot the kernel I compiled in a
Cygwin under Windows 7.

So I copied over the compiled binary, put it in my NetBSD VM, crossed my fingers
and rebooted.

I am very impressed by the build.sh system of NetBSD.
