[Bug 1576341] Re: systemd in degraded state on startup in LXD containers

[Mathew Hodson]

open-iscsi (2.0.874-4ubuntu1) artful; urgency=medium

  * Merge with Debian unstable. Remaining changes:
    - debian/tests: Add Ubuntu autopkgtests.
    - debian/iscsi-network-interface.rules, debian/net-interface-handler,
      debian/open-iscsi.install:
      Prevent network interface that contains iscsi root from bouncing
      during boot or going down during shutdown.
      Integrates with resolvconf and initramfs code that writes
      /run/initramfs/open-iscsi.interface
    - debian/open-iscsi.maintscript: clean up the obsolete
      iscsi-network-interface upstart job, file on upgrade.
    - Let iscsid systemd job run in privileged containers but not in
      unprivileged ones
    - Start open-iscsi systemd job when either /etc/iscsi/nodes or
      /sys/class/iscsi_session have content
      Based on patch by Nish Aravamudan, thanks! (LP #1576341)
    - add IPv6 support
      + add support for IPV6{DOMAINSEARCH,DNS0,DNS1} to net-interface-handler
        LP #1621507
      + Source /run/net6-*.conf when needed.
      + debian/extra/initramfs.local-top: handle IPv6 configs being
        shipped in DEVICE6 or /run/net6-*.conf in the initramfs, so we
        can fill in /run/initramfs/open-iscsi.interface (LP #1621507)
  * Drop:
    - d/extra/initramfs.local-top: When booting from iBFT,
      set the PROTO= entry in /run/net-*.conf accordingly,
      so that other tools, such as cloud-init, can use that
      information. (cloud-init fails if the current PROTO=none
      is used.) (LP: #1684039) (Closes: #866213)
      [ Fixed in Debian 2.0.874-4 ]
  * d/t/test-open-iscsi.py: drop test_daemon test
    - With the updates to the systemd units, the services do not run
      unless iSCSI is configured.

Bug description:
  The ubuntu:xenial image shows 'degraded' state in lxd on initial boot.

  $ lxc launch xenial x1
  $ sleep 10
  $ lxc file pull x1/etc/cloud/build.info -
  build_name: server
  serial: 20160420-145324

  $ lxc exec x1 systemctl is-system-running
  degraded

  $ lxc exec x1 -- systemctl --state=failed
    UNIT                          LOAD   ACTIVE SUB    DESCRIPTION
  ● dev-hugepages.mount           loaded failed failed Huge Pages File System
  ● iscsid.service                loaded failed failed iSCSI initiator daemon (iscsid)
  ● open-iscsi.service            loaded failed failed Login to default iSCSI targets
  ● systemd-remount-fs.service    loaded failed failed Remount Root and Kernel File Systems
  ● systemd-sysctl.service        loaded failed failed Apply Kernel Variables
  ● lvm2-lvmetad.socket           loaded failed failed LVM2 metadata daemon socket
  ● systemd-journald-audit.socket loaded failed failed Journal Audit Socket

  LOAD   = Reflects whether the unit definition was properly loaded.
  ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
  SUB    = The low-level unit activation state, values depend on unit type.

  7 loaded units listed. Pass --all to see loaded but inactive units, too.
  To show all installed unit files use 'systemctl list-unit-files'.
