I am likely going to simply track file changes and revert them for a reset to factory defaults facilitation, rather than maintaining a build system for a custom bsd.rd.
One assumption that I have made is that newfs and dd altroot to root and reboot in rc.securelevel would fail or be problematic? Is there any chance that OpenBSD would be interested in patches to add an unattended install option similar to how an auto_upgrade.conf is detected but where an /auto_install.conf is detected? I believe that the current autoinstall procedure requires interactivity (A) key or netboot.
