What is the usual way to pass this change to the kernel from your boot loader?
A.
Start in runlevel 1
B.
Pass init=/bin/sh on the kernel parameter line
C.
Pass /bin/sh on the kernel parameter line
D.
Pass start=/bin/sh on the kernel parameter line
Explanation:
If you use lilo or GRUB you can easily edit the kernel parameter line; any process specified by init=<command> will be executed with root privileges.
