defaultenv-2: trigger DHCP before booting 'net'
Some variables may be set from DHCP requests, as shown below: barebox@ZII VF610 Development Board, Rev C:/ echo $global.hostname dev-rev-c barebox@ZII VF610 Development Board, Rev C:/ echo $global.net.server 0.0.0.0 barebox@ZII VF610 Development Board, Rev C:/ dhcp eth0: 100Mbps full duplex link detected T T T eth0: DHCP client bound to address 192.168.203.31 barebox@ZII VF610 Development Board, Rev C:/ echo $global.hostname zii-dev-rev-c-1 barebox@ZII VF610 Development Board, Rev C:/ echo $global.net.server 192.168.203.1 barebox@ZII VF610 Development Board, Rev C:/ These variables are used by the boot/net script, so it is necessary to trigger DHCP before we set the TFTP file paths, otherwise booting from net will fail like below and will need to be triggered twice: running /env/bin/init...
