This bug was fixed in the package systemd - 232-21ubuntu7 --------------- systemd (232-21ubuntu7) zesty; urgency=medium
* networkd: accept `:' in ifnames in systemd/networkd. (LP: #1714933) * networkd: add support for ActiveSlave and PrimarySlave netdev options. (LP: #1709135) * Cherrypick upstream fix for a race between .mount and .automount units, which currently may result in automounts hanging. (LP: #1709649) * systemd.postinst: Fix-up version number check in the previous sru. The version check in the postinst was too tight, thus the SRU fix failed validation. (LP: #1710410) systemd (232-21ubuntu6) zesty; urgency=medium * link: Fix offload features initialization. This fixes a regression introduced in v232 which caused TCP segmentation offloads being disabled by default, resulting in significant performance issues under certain conditions. (Closes: #864073) (LP: #1703393) * loginctl: Fix loginctl ignoring user given session IDs at command-line (LP: #1682154) * Disable fallback DNS servers. This causes resolved to call-home to google, attempt to access network when none is available, and spams logs. (LP: #1449001) * initramfs-tools: trigger udevadm add actions with subsystems first. This updates the initramfs-tools init-top udev script to trigger udevadm actions with type specified. This mimicks the systemd-udev-trigger.service. Without type specified only devices are triggered, but triggering subsystems may also be required and should happen before triggering the devices. This is the case for example on s390x with zdev generated udev rules. (LP: #1713536) * Enable systemd-resolved by default. (LP: #1710410) * core: fix systemd failing to serialize tasks correctly on daemon-reload.

[Solution] trigger udev subsystems and devices, in the initramfs, in that order. [Testcase] Boot s390x system with chzdev configured devices, and cio_ignore=all kernel command line parameter. The chzdev configured devices should still be discovered on boot. [Original Bug report] The udev initramfs-tools boot script does not trigger subsystem "add" uevents. As a result, udev rules that listen to subsystem "add" events are never activated. This problem exists on at least Ubuntu 16.04 and 17.10. On s390, this results in a boot failure if the kernel is configured to start with an active device black list (kernel parameter cio_ignore=all,!condev). An example for an affected udev rule looks like this: ACTION=="add", SUBSYSTEM=="subsystem", KERNEL=="ccw", RUN{program}+="/bin/sh -c 'echo free 0009,ec30,ec32,f5f0-f5f2 > /proc/cio_ignore'" A proposed fix would be: Modify /usr/share/initramfs-tools/scripts/init-top/udev: Replace line udevadm trigger --action=add with udevadm trigger --type=subsystems --action=add udevadm trigger --type=devices --action=add This would also be consistent with the steps that the systemd udev coldplug unit file performs (see /lib/systemd/system/systemd-udev- trigger.service). [Regression Potential] More udev rules will be now triggered, earlier, during initramfs stage of boot rather than post-pivot-root. However, this is inline with current rootfs behaviour and thus should not regress behaviour - simply some rules will get triggered earlier.
