 NAME    [Toc]    [Back]
      krsd - kernel registry services daemon

 SYNOPSIS    [Toc]    [Back]
      krsd -1

      krsd [-i] [-d seconds]

 DESCRIPTION    [Toc]    [Back]
      krsd saves data, flagged as persistent in the core kernel KRS tree, to
      files on disk.  These files are read when the system is booted, in
      order to restore the aforementioned persistent data.

      When running in daemon mode, krsd sleeps, waking periodically to check
      if any persistent data have changed since the last save.  If
      persistent data have changed, the new state of the data is saved to
      disk.  Otherwise, krsd sleeps for another period of time and then
      repeats the process.

      When running in one time (non-daemon) mode, krsd unconditionally saves
      persistent data to disk and then exits.

      Normally, krsd is executed in daemon mode by init(1M).  The
      /etc/inittab entry for krsd will cause krsd to be respawned
      automatically if it is terminated.

      krsd uses the syslog message logging facility to log all krsd
      activity.

      Persistent KRS data are maintained in files based on the class of the
      data in question.  Currently, the following classes are recognized:

           system specific
                Data that apply to the system in general, regardless of what
                configuration is booted.  This data is saved in the file
                system.krs.

           configuration specific
                Data specific to a given bootable configuration.  This data
                is saved in the file config.krs.

    Options    [Toc]    [Back]
      krsd recognizes the following options:

      -1           One time mode, unconditionally save persistent data to
                   disk, then exit.

      -i           Run from inittab, parent does not spawn a child nor exit.
                   Required if respawn from inittab is to work properly.

      -d seconds   Set the delay time to seconds seconds.  This is the time
                   interval between attempted saves of persistent data.  The
                   default interval is 300 seconds.
