SYS-UNCONFIG(8)             System Manager's Manual            SYS-UNCONFIG(8)



NAME
       sys-unconfig - undo a system's configuration

SYNOPSIS
       /usr/etc/install/sys-unconfig

DESCRIPTION
       sys-unconfig  packs  up  a  machine  to  make it ready to be configured
       again.

       It restores a systems's configuration to an "as-manufactured" state.  A
       system's  configuration  consists of hostname, Network Information Ser-
       vice (NIS) domain name, timezone and IP address.

       sys-unconfig does the following:

              o    Restores the default /etc/hosts file.

              o    Removes the default hostname in /etc/hostname.??[0-9].

              o    Removes the default domainname in /etc/defaultdomain.

              o    Removes the default /usr/lib/zoneinfo/localtime file.

              o    Disables the Network Information Service (NIS) if  the  NIS
                   service was requested.

       When sys-unconfig is finished, it will perform a system shutdown.

       sys-unconfig  is potentially a dangerous utility and can only be run by
       the super-user.

FILES
       /etc/hosts
       /usr/lib/zoneinfo/localtime
       /usr/etc/install/sys_info

NOTES
       The Network Information Service (NIS) was formerly known as Sun  Yellow
       Pages  (YP).   The  functionality of the two remains the same; only the
       name has changed.
