Sadly, the dhclient-script shipped as part of isc-dhcp-client in Ubuntu unconditionally reads from /etc/fstab without checking for its existence. Since no package holds /etc/fstab, this file will not exist in the appliance, cause dhclient to fail (actually keep looping calling the failing dhclient-script) when the network is requested.
As a workaround, touch /etc/fstab just before enabling the network: if that file exists nothing changes, while an empty file will be available in the other case, making at least dhclient-script in Ubuntu working. --- appliance/init | 1 + 1 file changed, 1 insertion(+)
