Set the

.It Sy dhclient
YES or NO.
Set to YES to configure some or all network interfaces using
the DHCP client. If you set
.Sy dhclient
to YES, you must either set
.Sy critfs_require_network
to NO or direct the DHCP client to store the leases file on the root
filesystem by modifying the
.Sy dhclient_flags
variable. You must not provide ifconfig information or ifaliases
information for any interface that is to be configured using the DHCP
client. Interface aliases can be set up in the DHCP client configuration
file if needed - see
.Xr dhclient.conf 5
for details.
.It Sy dhclient_flags
Flags to pass to the DHCP client. See
.Xr dhclient 8
for complete documentation. If you wish to configure all broadcast
network interfaces using the DHCP client, you can leave this blank.
To configure only specific interfaces, name the interfaces to be configured
on the command line.

If you must run the DHCP client before mounting critical filesystems,
then you should specify an alternate location for the DHCP client's lease
file in the
.Sy dhclient_flags
variable - for example, "-lf /tmp/dhclient.leases".
