I tested maas's command line as well. /proc/cmdline from a maas pxe boot is BOOT_IMAGE=ubuntu/amd64/hwe-y/yakkety/daily/boot-kernel nomodeset iscsi_target_name=iqn.2004-05.com.ubuntu:maas:ephemeral-ubuntu-amd64-hwe-y-yakkety-daily iscsi_target_ip=192.168.1.5 iscsi_target_port=3260 iscsi_initiator=bonusvm2 ip=::::bonusvm2:BOOTIF ro root=/dev/disk/by-path/ip-192.168.1.5:3260-iscsi-iqn.2004-05.com.ubuntu:maas:ephemeral-ubuntu-amd64-hwe-y-yakkety-daily-lun-1 overlayroot=tmpfs cloud-config-url=http://192.168.1.5/MAAS/metadata/latest/by-id/4y3h7t/?op=get_preseed log_host=192.168.1.5 log_port=514 initrd=ubuntu/amd64/hwe-y/yakkety/daily/boot-initrd BOOTIF=01-52-54-00-ca-c0-9e

[Test Case] * Create a machine that boots using an nfsroot. * Use ip=:::::eth0:dhcp on the kernel command line. To set up networking. * Discover that the device never comes up because, networking is not configured correctly. [Regression Potential] * Regressions potential is limited to machines using ip={""|::::*|on|any|dhcp} on the kernel command line. As this is already broken regression potential is minimal. This is common on machines that use nfsroot or otherwise pxe boot. [Other Info] * There are a number of other issues in this code base that are not solved by this fix. * The networking configuration does not strictly follow the kernel documentation as described https://www.kernel.org/doc/Documentation/filesystems/nfs/nfsroot.txt . This should be fixed. ====================Original Bug Description Follows================== initramfs-tools 0.122ubuntu8.3 introduced a serious regression where networking is not initialized when the boot option "ip=dhcp" is provided. We are seeing this problem in AWS, but cannot confirm if this issue is specific to AWS or will occur with different hardware or in different environments. Removing "ip=dhcp" from the boot options with 0.122ubuntu8.3 results in networking being configured. The issue does not occur with 0.122ubuntu8.2 or previous versions when "ip=dhcp" is set. AWS has no console so debugging is not a trivial task. I do have a console log with some output, and will update this bug shortly with it.
