I think this put system to something like runlevel S or 1

When system goes though runlevel S, there is some SULOGIN things:

$ grep -i login *
S02early-readahead:         if [ -d /proc/1 ] && [ ! -e /proc/1/loginuid ]; then
S08checkroot.sh:[ "$SULOGIN" ] || SULOGIN=no
S08checkroot.sh:        # Set SULOGIN in /etc/default/rcS to yes if you want a sulogin to
S08checkroot.sh:        [ "$SULOGIN" = yes ] && sulogin -t 30 $CONSOLE
S08checkroot.sh:                if ! sulogin $CONSOLE
S08checkroot.sh:                if ! sulogin $CONSOLE
S12checkfs.sh:                  if ! sulogin $CONSOLE
S25bootmisc.sh:[ "$DELAYLOGIN" ] || DELAYLOGIN=yes
S25bootmisc.sh: # If login delaying is enabled then create the flag file
S25bootmisc.sh: # which prevents logins before startup is complete
S25bootmisc.sh: case "$DELAYLOGIN" in
S25bootmisc.sh:         echo "System bootup in progress - please wait" > /var/lib/initscripts/nologin
S25bootmisc.sh: # Create /var/run/utmp so we can login.
S25later-readahead:         if [ -d /proc/1 ] && [ ! -e /proc/1/loginuid ]; then
S26stop-bootlogd-single:# a call to /sbin/sulogin, while runlevel 1 is a call to
S26stop-bootlogd-single:# /sbin/sulogin.
....

OK, I found
S08checkroot.sh:        [ "$SULOGIN" = yes ] && sulogin -t 30 $CONSOLE

It has comments:
        # Set SULOGIN in /etc/default/rcS to yes if you want a sulogin to
        # be spawned from this script *before anything else* with a timeout,
        # like sysv does.

See sulogin(8).

Cheers.
