idconfupdate(1M)                                    idconfupdate(1M)


       NAME
             idconfupdate - update system configuration files

       SYNOPSIS
             idconfupdate [-f] [-o file] [-s] [-r confdir]

       DESCRIPTION
             The idconfupdate command ensures that the system configuration
             files on disk are consistent with the current system
             configuration, as defined by the in-core Resource Manager
             database.

             When idconfupdate is invoked without options, it reads the
             Resource Manager database from /dev/resmgr, and performs two
             functions:

             1.    It saves the Resource Manager database in /stand/resmgr
                   so that the database will be available for reboots.  If
                   idconfupdate is not run after changes are made to the
                   in-core Resource Manager database, those changes will be
                   lost when the system is rebooted.

             2.    It updates the parameters for hardware drivers in the
                   /etc/conf/sdevice.d files to agree with those provided
                   by the Resource Manager.

                   Only sdevice files for hardware drivers are affected; a
                   hardware driver is identified by having an h in the
                   flags field of its Master file.

                   All drivers that are not in the Resource Manager
                   database are turned off.  That is, the config field of
                   each line in their sdevice files is changed from Y to N.

             When idconfupdate is invoked with the -s option, the Resource
             Manager database is constructed using the sdevice files.  The
             -o option must be specified with the -s option to prevent a
             user from accidentally overwriting /stand/resmgr.

          Options:
             -f      Force idconfupdate to create a new database and update
                     the sdevice files even if the resmgr's timestamp
                     indicates that no update is necessary.

            -o file Save the resmgr database in the given file; file
                    defaults to /stand/resmgr if not given.  The -o option
                    must be specified if the -s option is used, for
                    safety.

            -r confdir
                    Override the built-in /etc/conf path, so an alternate
                    root may be specified, for example, idconfupdate -r
                    $ROOT/$MACH/etc/conf.

            -s      Read the current sdevice files and create a resmgr
                    database based on them.  The -o option must be
                    specified when using the -s option to avoid
                    accidentally destroying the /stand/resmgr system
                    database.
