auto_parms(1M)auto_parms(1M)NAMEauto_parms - initial system configuration plus DHCP support command
The 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 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 inter‐
face. See the rc(1M) manpage for information about for invocation con‐
While checking for availability of a lease on each interface, also con‐
sults 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"

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 sys‐
tem's hostname is not yet set), it invokes 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 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
placing in "lease maintenance mode" prior to exiting.
