I tried in two ways:
1) inserted ifconfig eth0 192.168.0.11 netmask 255.255.255.0 up in to the bootlocal.sh
2) insert /opt/eth0.sh with the ifconfig eth0 192.168.0.11 netmask 255.255.255.0 up
on bootlocal.sh to load on startup.
Everytime I did backup but after the reboot, no eth0!!!only lo with the ifconfic command appear.
then the ifconfig eth0 192.168.0.11 netmask 255.255.255.0 up
worked, but I wanted on startup.
