Is there a way to stop someone with physical access to the box from booting into single user mode and changing the root password? I'm not interested in solutions that require setting a boot or poweron password in the BIOS. I'd like something that could be done in the Linux kernel, so as to apply to multiple platforms.
AFAIK you don't need a kernel patch for that. Just edit your inittab, so init calls whatever you like it to call instead. Anyway, I do not recommend this, since single-user-mode is a valuable measure for troubleshooting a machine. If you want to secure a box I suggest you rather lock it away.
