9.3. Booting into Single-User Mode
One of the advantages of single-user mode is that you do not need a boot
diskette or CD-ROM; however, it does not give you the option to mount
the file systems as read-only or not mount them at all.
In single-user mode, your computer boots to runlevel 1. Your local file
systems are mounted, but your network is not activated. You have a
usable system maintenance shell. Unlike rescue mode, single-user mode
automatically tries to mount your file system; do
not use single-user mode if your file system can not be
mounted successfully. You can not use single-user mode if the runlevel 1
configuration on your system is corrupted.
If your system boots, but does not allow you to log in when it has
completed booting, try single-user mode.
If you are using GRUB, use the following steps to boot into single-user

that you wish to boot and type e for edit. You
will be presented with a list of items in the configuration file

Select the line that starts with
kernel and type
e to edit the line.
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.
Back at the GRUB screen, type b to boot into
single-user mode.
If you are using LILO, at the LILO boot prompt (if you are using the
graphical LILO, you must press
[Ctrl]-[x] to exit the
graphical screen and go to the boot:
prompt) type:
