Bug Description

After installing NetworkManager in a fresh vivid VM, NetworkManager-wait-online.service is disabled. We should consider enabling it on systems which don't have any static interfaces in /etc/network/interfaces, so that units that need network-online.target work properly.

Michael points out that this is blocked on having rcS init.d scripts which have Required/Should-Start: $network or $remote_fs, otherwise it's too easy to get dependency cycles.

Martin Pitt (pitti) wrote :

At the moment, a default installation has these rcS init.d scripts:

  apparmor console-setup ifupdown lvm2 lvm networking qemu-kvm qemu-system-x86

Of those only console-setup.service has Required-Start: $remote-fs, and none of them have $network.

For the record, that's the command to check this:

grep -l DefaultDependencies /run/systemd/generator.late/*.service | xargs egrep 'remote-fs|network-online'

Note: "Before=network.target" is broken, this should be After=. This leads to dependency cycles easily.

Martin Pitt (pitti) wrote :

So, if you want to try and enable this, do:

 * edit /etc/init.d/console-setup and replace $remote_fs with $local_fs (this will break with /var on NFS!)
 * edit /lib/systemd/system/NetworkManager-wait-online.service to drop "network.target" in the Before= line
 * run "sudo systemctl enable NetworkManager-wait-online.service"

I confirm the instructions in comment #6 have solved my issue with nfs mounts at boot.

This bug was fixed in the package console-setup - 1.108ubuntu4

---------------
console-setup (1.108ubuntu4) vivid; urgency=medium

  * Add systemd unit for console-setup. That avoids waiting for $remote_fs
    during early boot. (Note: there is no need to enable it, it gets pulled
    in through systemd-vconsole-setup.service) (LP: #1430280)

---------------
network-manager (0.9.10.0-4ubuntu10) vivid; urgency=medium

  * Add fix-NetworkManager-wait-online.service.patch: Fix dependencies of
    NetworkManager-wait-online.service to avoid dependency loops and delays,
    and install it into the correct target. (Pre-requisite for LP #1430280)
  * debian/rules: Enable NetworkManager-wait-online.service. This will make
    network-online.target wait for connectivity, to fix NFS mounts and other
    units which depend on it. (LP: #1430280)
  * debian/network-manager.postinst: Flush deb-systemd-helper status of
    NM-wait-online to get it enabled on upgrades to this version.
