This feature may only be available on certain systems where +\fBinit\fR +has been modified accordingly, or where the +/etc/inittab +has an entry for a single user login\&. +.PP +The user is prompted +.PP +Type control\-d to proceed with normal startup, (or give root password for system maintenance): +.PP +Input and output will be performed with the standard file descriptors unless the optional device name argument is provided\&. +.PP +If the user enters the correct root password, a login session is initiated\&. When +\fIEOF\fR +is pressed instead, the system enters multi\-user mode\&. +.PP +After the user exits the single\-user shell, or presses +\fIEOF\fR, the system begins the initialization process required to enter multi\-user mode\&. +.SH "CAVEATS" +.PP +This command can only be used if +\fBinit\fR +has been modified to call +\fBsulogin\fR +instead of +/bin/sh, or if the user has set the +\fIinittab\fR +to support a single user login\&. For example, the line: +.PP +co:s:respawn:/etc/sulogin /dev/console +.PP +should execute the sulogin command in single user mode\&. +.PP +As complete an environment as possible is created\&.
