need to set static IP for network without DHCP

[natoriousbigg]

Your script works great. But FYI, if you're working with a network without DHCP, you have to specific a static in during the initramfs otherwise you're going to get locked out.

Need to add a line "IP=" with your settings into /etc/initramfs-tools/initramfs.conf
