Its actually pretty simple. You just install Netbsd on a machine with OF 1.0.5 and it does all of it for you. One thats done, you set your boot device to /path/to/:0 and it works. Same applies to booting the cd to install. boot /path/to/:0 and it boots right up. As far as Linux, the installer should also do the dirty work for you as long as it can have an entire drive and you've specified that you either want a ~100mb ext2 file-system as /boot, or you've made your / ext2. I highly recommend that you use the first option. Ext2 is ancient and you WILL loose data if your machine doesn't unmount it cleanly. The linux installer should install quik for you, and then you would set your boot device to /path/to/:0 . Simple as that .

As far as which OS to pick, I think its too early for me to go into that conversation.
