Attaching a tarbal of everything i have in /var/log, not sure it's useful (not my "ephemeral" environment is read-only with /var/log on a tmpfs, so it's mostly empty).
Also here's my exact /proc/cmdline from within the booted ephemeral environment: BOOT_IMAGE=vmlinuz-4.4.0-42-generic initrd=initrd.img-4.4.0-42-generic root=/dev/nfs nfsroot=10.17.76.1:/var/lib/tribble/ephemeral ip=dhcp ro nomodeset net.ifnames=0 BOOTIF=01-80-fa-5b-36-f5-86 ** Attachment added: "log.tgz" https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/1631474/+attachment/4760012/+files/log.tgz -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to initramfs-tools in Ubuntu. https://bugs.launchpad.net/bugs/1631474 Title: No networking with initramfs-tools 0.122ubuntu8.3 and ip=dhcp boot option Status in initramfs-tools package in Ubuntu: In Progress Status in initramfs-tools source package in Xenial: Confirmed Status in initramfs-tools source package in Yakkety: In Progress Bug description: [Impact] * 0.122ubuntu8.3 of initramfs-tools no longer correctly processed ip=dhcp or ip=:::::eth0:dhcp * Regression-updates * The fix better parses the ip= command line argument. [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 ?*:?*:?*:?*: use case falls through to the default case, and likely breaks there. As such static assignment via ip= appears broken - * 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.
