SERIES 3000 Version 1.0
Workstation Administration
4.2.3 Entering Multi-user Mode Automatically
By default, the IRIS workstation boots into single-user mode, which should be
used only for system maintenance. When the system is running in single-user
mode, only the root file system is mounted, none of the system daemons are
started, and the terminal lines do not allow users to log in. To enter multi-user
mode, the super-user issues the multi command.
The super-user can also edit the file /etc/inittab so that the system automatically
enters multi-user mode each time it is booted. The first line of /etc/inittab tells
init which mode to enter after booting U

The system will now enter multi-user mode each time it is rebooted. For more
information on the init process, see init (1M) and inittab (4).

Configuration Files
The directories /etc and /usr/lib contain the major system configuration files.
They can be edited by the system administrator as needed to serve the needs of
the local user community.
/etc/bcheckrc This file contains commands to perform a file
system check, and to set the date using /etc/rc.getdate
if possible, or to prompt for the date if not.
/etc/checklist This file lists the file systems processed by default
by fsck .
/etc/cshrc This file is read at login by accounts that specify the
C shell as the login shell. It contains commands
that define the user’s environment. See csh (1) and
cshrc (4).
/etc/gettydefs This file contains entries for line speeds and
terminal settings used by getty (1M) for initializing
devices. See gettydefs (4).
/etc/group This file contains the list of groups that are used to
control access to files. See Section 4.2 and group (4).
