 auto_parms(1M)                                               auto_parms(1M)

 NAME    [Toc]    [Back]
      auto_parms - initial system configuration plus DHCP support command

 SYNOPSIS    [Toc]    [Back]

 DESCRIPTION    [Toc]    [Back]
      The auto_parms command is a system initialization command that handles
      first-boot configuration, that is, the setting of unique system
      "initial identity parameters", and ongoing management of DHCP
      lease(s).  The auto_parms command is invoked at boot time by the
      /sbin/rc command.  Initially it loads a list of available ethernet
      interfaces and requests a DHCP lease on each interface.  It stops when
      a valid lease is secured or the list is exhausted.

      While checking for availability of a lease on each interface,
      auto_parms also consults /etc/rc.config.d/netconf and examines the
      variable DHCP_ENABLE[index].  If it is set to "1", auto_parms attempts
      to request a lease on the the interface designated by index.  If
      DHCP_ENABLE[index] is set to "0" (the default case) or is absent from
      /etc/rc.config.d/netconf, auto_parms does not attempt a DHCP request
      on that interface.

      Once a lease is secured, the information supplied with the lease is
      used to initialize key networking parameters; see dhcpdb2conf(1M).

      If auto_parms detects that the system is undergoing "first-boot"
      (meaning the system's hostname is not yet set), it invokes set_parms
      and geocustoms to verify the DHCP-supplied parameters and to collect
      any parameters not supplied by DHCP.

      For all subsequent boots, the data supplied by a DHCP lease is assumed
      by auto_parms to be correct.  Note that in a (non-mobile) environment
      where DHCP is used for IP address management, under normal conditions
      the lease information should not change between reboots.  This is
      accomplished by auto_parms placing dhcpclient in "lease maintenance
      mode" prior to exiting.

 EXAMPLES    [Toc]    [Back]
      See /sbin/rc for invocation context.
