Init INIT(8) - System Manager’s Manual # INIT(8) - System Manager’s Manual
NAME # init - process control initialization
SYNOPSIS # init [-fs]
DESCRIPTION # The init program is the last stage of the boot process. It normally executes the sequence of events described in rc(8) and begins multi-user operation.
The kernel may pass the following options to init, usually when requested by the boot(8) program:
-f
Activate fastboot mode. This is not currently supported by the OpenBSD kernel.

INSTALLBOOT(8) - System Manager’s Manual (alpha) # INSTALLBOOT(8) - System Manager’s Manual (alpha)
NAME # installboot - install disk bootstrap software
SYNOPSIS # installboot [-nv] boot bootxx rawdiskdevice
DESCRIPTION # The installboot utility prepares a disk for bootstrapping.
The OpenBSD/alpha disk bootstrap software is split into two parts: a small first-stage boot program that is written into the disklabel area of a disk (and hence is limited in size to 7680 bytes) , and a second-stage boot program that resides in the filesystem proper (typically with the name /boot) .

LDATTACH(8) - System Manager’s Manual # LDATTACH(8) - System Manager’s Manual
NAME # ldattach - attach a line discipline to a serial line
SYNOPSIS # ldattach [-27dehmop] [-s baudrate] [-t cond] discipline device
DESCRIPTION # ldattach is used to attach a line discipline to a serial line to allow for in-kernel processing of the received and/or sent data. Depending on the line discipline being attached, one or more options may be applied.

POWER(4) - Device Drivers Manual (landisk) # POWER(4) - Device Drivers Manual (landisk)
NAME # power - power switch
SYNOPSIS # power0 at obio?
DESCRIPTION # Landisk models provide an interrupt when the power switch is flipped to the Off position. The power driver catches that interrupt. If the hw.allowpowerdown sysctl(8) is set to 1, power will signal init(8) to do a clean shutdown.
SEE ALSO # intro(4), obio(4), init(8), rc.

POWER(4) - Device Drivers Manual (sparc64) # POWER(4) - Device Drivers Manual (sparc64)
NAME # power - power button
SYNOPSIS # power* at ebus?
DESCRIPTION # Some UltraSPARC host bridges provide an interrupt when the power button is depressed. The power driver catches that interrupt. If the hw.allowpowerdown sysctl(8) is set to 1, power will signal init(8) to do a clean shutdown.
SEE ALSO # ebus(4), intro(4), init(8), rc.shutdown(8), sysctl(8)

RC.CONF(8) - System Manager’s Manual # RC.CONF(8) - System Manager’s Manual
NAME # rc.conf, rc.conf.local - system daemon configuration database
DESCRIPTION # The file rc.conf contains a series of variable assignments that are used to configure the system daemons. These variables are read by rc(8) early on in the boot sequence and every time an rc.d(8) script is executed.
It is advisable to leave rc.conf untouched, and instead create and edit a new rc.
...
RC.SHUTDOWN(8) - System Manager’s Manual # RC.SHUTDOWN(8) - System Manager’s Manual
NAME # rc.shutdown - command script run at system shutdown
DESCRIPTION # When the system is shut down using the reboot(8) or halt(8) commands, or when init(8) is signalled to do so, or when a keyboard-requested halt is issued (if the architecture supports it), rc(8) is invoked with the argument “shutdown”. This document details the actions taken by rc(8) in such an instance.

RC(8) - System Manager’s Manual # RC(8) - System Manager’s Manual
NAME # rc, rc.firsttime, rc.local, rc.securelevel - command scripts for system startup
DESCRIPTION # rc is the command script that is invoked by init(8) when the system starts up. It performs system housekeeping chores and starts up system daemons. Additionally, rc is intricately tied to the netstart(8) script, which runs commands and daemons pertaining to the network. rc is also used to execute any rc.

SECURELEVEL(7) - Miscellaneous Information Manual # SECURELEVEL(7) - Miscellaneous Information Manual
NAME # securelevel - securelevel and its effects
DESCRIPTION # The OpenBSD kernel provides four levels of system security:
-1 Permanently insecure mode
init(8) will not attempt to raise the securelevel may only be set with sysctl(8) while the system is insecure otherwise identical to securelevel 0 0 Insecure mode
used during bootstrapping and while the system is single-user all devices may be read or written subject to their permissions system file flags may be cleared with chflags(2) 1 Secure mode

TTYS(5) - File Formats Manual # TTYS(5) - File Formats Manual
NAME # ttys - terminal initialization information
DESCRIPTION # The ttys file contains information that is used by various routines to initialize and control the use of terminal special files. This information is read with the getttyent(3) library routines.
There is one line in the ttys file per special device file. Fields are separated by tabs and/or spaces. Fields comprised of more than one word should be enclosed in double quotes (’"’).
