Single-User Mode

When I was configuring a GuruPlug for the company I work for I got stuck at the loginscreen. So I searched the world wide web for a way to access the debian installation in Single-User Mode so I can correct my misstake. After a while I found a some lines of code to do that. So here is a little HowTo how to get in Single-User Mode

Access single-user mode

• connect GuruPlug to your computer with the devkit
• Access the GuruPlug via UART on /dev/ttyUSBx
• Power on the GuruPlug
• Press any key at boot when promted to access the bootmanager
• add "init=/bin/bash" to the kernelparameters and boot by executing the following commands

> setenv x_bootargs ${x_bootargs} init=/bin/bash
> saveenv

• Boot the system in singel-user mode

> boot

Restore original kernelparameters

• reboot GuruPlug by executing the following command

> reboot -f

• As before press any key at boot when promted to access the bootmanager
• print the kernelparameters by executing the following command

> printenv x_bootargs

• Copy all parameters expect "init=/bin/bash"
• execute the following commands with the copied parameters to remove the "init=/bin/bash"

> setenv x_bootargs <copied kernelparameters>
> saveenv

• Boot the system

> boot
