The referenced upstream bug report shows that upstream agrees this is a regression in systemd behavior which they are planning to correct, which is reasonable.
However, I think this is also a bug in the kdump-tools package. 'default.target' is a meta-target, which no package can know whether it's appropriate to start its service under without knowing what default.target is set to. In particular, kdump-tools also declares 'Wants=network-online.target'. If default.target (either on the kernel commandline or on the filesystem) is pointed to some sort of local-only rescue target, having network-online pulled into this target via kdump- tools could break the boot. I think kdump-tools in Debian and Ubuntu should instead be integrating with multi-user.target. ** Changed in: systemd (Ubuntu) Importance: Undecided => High ** Changed in: systemd (Ubuntu) Status: New => Triaged ** Also affects: makedumpfile (Ubuntu) Importance: Undecided Status: New ** Changed in: makedumpfile (Ubuntu) Assignee: (unassigned) => Canonical Foundations Team (canonical-foundations) ** Changed in: systemd (Ubuntu) Assignee: Ubuntu on IBM Power Systems Bug Triage (ubuntu-power-triage) => Canonical Foundations Team (canonical-foundations) ** Changed in: ubuntu-power-systems Assignee: Canonical Foundations Team (canonical-foundations) => (unassigned) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1708409 Title: kdump service does not start after configure/reboot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1708409/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
