I just got it working. Took me longer than it should, but the important thing is, it works.
So, if you wanna avoid my mistakes, here's what to do:
- Before compiling the kernel, konfigure it properly, as outlined on http://cosi.clarkson.edu/docs/kernel/setup/uml/uml.html
- If you encounter compiling problems, believe there's a way and google for it (see my previous post for 2.6.17-related issues).
- Don't waste time on creating and configuring your own filesystem on Ubuntu 7.10, because the one for 7.04 works.
