Hi Ruud,

Linus Torvalds is another counterexample to that.

I recently read his book "Just for fun" (or actually the Finnish 
translation by his sister). It certainly was a huge task to implement 
enough system calls to get /bin/sh running. Other major early 
accomplishments include the VT-100 emulator that still exists in the 
Linux text console and the VFS layer and the first file systems. I guess 
that the next major accomplishment after /bin/sh was to get GCC running 
on Linux, so that he no longer had to boot to Minix for development.

As far as I understand, other contributors entered the picture only 
after Linux had become independent of Minix.

(I am not suggesting that your goal should be a self-hosting 
environment. I think that cross-compiling makes perfect sense. I guess 
nobody develops Android applications on Android, for example.)

Seasons greetings,
