[Bug 1814818] Re: Skip enslaved devices during boot

[Launchpad Bug Tracker]

This bug was fixed in the package initramfs-tools - 0.131ubuntu15.1

---------------
initramfs-tools (0.131ubuntu15.1) cosmic-security; urgency=medium

  * scripts/functions: include a new option to skip enslaved network
    devices. (LP: #1814818)
      Include the new variable NETWORK_SKIP_ENSLAVED. When set to a
      value different than "0", this variable will cause any enslaved
      network devices to be skipped from the list of netbootable
      devices. This variable can be set via the configuration files
      under /etc/initramfs-tools/ or via any configuration file under
      the initrd directory /conf/conf.d/ via a hook script.

  Skip enslaved devices during boot

Bug description:
  [Impact]

  In some scenarios, we need to skip enslaved network devices from being
  brought up in initrd.

  In order to avoid regressions for other users, the new behaviour is
  being conditioned to the configuration variable NETWORK_SKIP_ENSLAVED.
  This mechanism enable us to use it only for the required kernels. The
  target kernel should be responsible to include the configuration via
  an initramfs-tools hook.

  [Test Case]

  Enslaved network devices shouldn't be brought up when the
  configuration is set by certain kernels. For any other scenario, such
  as the generic Ubuntu kernel, the behaviour should not be changed.

  [Regression Potential]

  The potential for regressions was vastly reduced by conditioning the
  new behaviour.
