This shouldn't happen.. The yaboot installation script executes: ybin -v read The output will be on-screen until you press enter.. anyway.. as i said before, you can use the slackintosh-installer cdrom to boot the installed system. You just have to append a 'root' to the kernel. Once bootet, you can try to fix the yaboot configuration..
