The single-user phase is simply to ensure that nothing is running that would interfere with the installworld/mergemaster steps. Therefore, an appropriate workaround if you cannot go to single user mode remotely would be to install the kernel, reboot into the new kernel, install world, reboot into the new world. However, if you have no remote access at all (remote power would be better than nothing!) this would be quite risky. Judicious use of nextboot, and having someone on standby who can find the power button is recommended. Cheers Tom
