How can I run radmind in Single User mode?

Startup into single-user mode

Disable Open Firmware Password (OFPW)
Note - OFPW will disable startup in single user mode

Restart or startup the Mac into the Open Firmware
(Press Command + Option + O + F keys)
Enter the following command & press return:

setenv security-mode none
Enter password at the prompt & press return.
Enter the following command & press return:

reset-all
This will restart the Mac

Repair & Mount Boot Volume

Enter the following command:

fsck -y
If you have journaling enabled, use the command:

fsck -yf

This will check the boot volume's file system, and attempt repair if necessary. Always do this first. Note that this may not be able to fix all problems in a single pass, so if it finds and fixes anything (it'll display "***** FILE SYSTEM WAS MODIFIED *****"), run it again, until it doesn't find any more errors.
Note, sometimes fsck will not properly repair the startup disk it is usually better to use third-party utility DiskWarrior or re-image the hard disk with Apple Software Restore (ASR) if you have a hard disk with continual problems, before running radmind.

Enter the following command:

mount -uw /

This command remounts the boot volume, enabling write access. You need to do this before you can change anything on disk.

Starting system daemons & components

Run Radmind

Then run the radmind tools. That's it! You could put all these steps into a script, and then you'd have only one command to execute after booting into single-user mode.

Re-enable OFPW

After radmind has completed make sure to enable Open Firmware Password either using Open Firmware, nvram, or Open Firmware GUI utility.
