NAME
auto_parms - initial system configuration plus DHCP support command
SYNOPSIS
DESCRIPTION
The command is a system initialization command that handles first-boot configuration, that is, the setting of unique system "initial iden-
tity parameters", and ongoing management of DHCP lease(s). The command is invoked at boot time by the command. Initially it loads a list
of available ethernet interfaces and requests a DHCP lease on each interface. See the rc(1M) manpage for information about for invocation
context.
While checking for availability of a lease on each interface, also consults and examines the variable If it is set to "1", attempts to
request a lease on the the interface designated by If is set to "0" (the default case) or is absent from 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 detects that the system is undergoing "first-boot" (meaning the system's hostname is not yet set), it invokes to verify the DHCP-sup-
plied parameters and to collect any parameters not supplied by DHCP.
For all subsequent boots, the data supplied by a DHCP lease is assumed by 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 accom-
plished by placing in "lease maintenance mode" prior to exiting.
