NAME
       sulogin - access single-user mode

SYNOPSIS
       sulogin

DESCRIPTION
       The  sulogin  utility  is  automatically invoked by init when the system is first started. It prompts the user to type the root password to
       enter system maintenance mode (single-user mode) or to type  EOF (typically <CTRL-D>) for normal startup (multi-user mode). The user should
       never directly invoke sulogin.

       The  sulogin utility can prompt the user to enter the root password on a variable number of serial console devices, in addition to the tra-
       ditional console device. See consadm(1M) and msglog(7D) for a description of how to configure a serial device to  display  the  single-user
       login prompt.

FILES
       /etc/default/sulogin    Default value can be set for the following flag:

			       PASSREQ	       Determines if login requires a password. Default is PASSREQ=YES.

       /etc/default/login      Default value can be set for the following flag:

			       SLEEPTIME       If  present,  sets  the number of seconds to wait before login failure is printed to the screen and
					       another login attempt is allowed. Default is 4 seconds. Minimum is 0 seconds. Maximum is 5 seconds.

					       Both su(1M) and login(1) are affected by the value of SLEEPTIME.
