Which option can you pass at the "LILO:" prompt to boot into single user mode?
a) linux 1
b) init 1
c) linux single
d) vmlinuz single
The correct answer for Redhat is "c" and "d" would work in Slackware.
This is especially useful if something goes wrong in your X configuration, and X11 cannot start up.
Here is info if you are using GRUB:
 If you are using GRUB, use the following steps to boot into single-user mode:
   1. If you have a GRUB password configured, type p and enter the password.
   2. Select Red Hat Linux with the version of the kernel that you wish to boot and type e for edit. You will be presented with a list of items in the configuration file for the title you just selected.
   
3.  Select the line that starts with kernel and type e to edit the line.
  
 4.  Go to the end of the line and type single as a separate word (press the [Spacebar] and then type single). Press [Enter] to exit edit mode.
   
5.  Back at the GRUB screen, type b to boot into single user mode. 
I don't use GRUB so I have no further details regarding this.
