[Bug 1764824] Re: [FFE] 'netplan try' feature in netplan 0.35

[Launchpad Bug Tracker]

This bug was fixed in the package netplan.io - 0.35

---------------
netplan.io (0.35) bionic; urgency=medium

  * debian/postinst: fix version check for when to write breadcrumbs.
    (LP: #1756742)
  * bonds/bridges: Support specifying time-based values with "ms" suffix when
    the value should be in milliseconds; while keeping support for the previous
    behavior of handling values are pure seconds when no suffix is present.
    (LP: #1745597)
  * IPv6: accept-ra should default to being unset, so that the kernel default
    can be used. (LP: #1732002)
  * DHCPv4: add a "dhcp-identifier: mac" field that can be set to fix interop
    with Windows Server-based DHCP servers which don't support RFC 4361.
    (LP: #1738998)
  * docs, examples: reformat comments in examples, add standalone example files
  * debian/docs, debian/netplan.io.install: install doc and examples in the
    right locations.
  * netplan try: allow users to preview/test and approve network configuration
    changes, and automatically revert if they are not accepted. (LP: #1764824)
  * networkd: don't wipe out /run/netplan on generate: we do want to keep any
    YAML configurations in that directory, we just need to remove generated
    wpasupplicant configs. (LP: #1764869)
  * debian/control: add bash-completion to Build-Depends to make sure we do
    install completion files in the right location.

Title:
  [FFE] 'netplan try' feature in netplan 0.35

Status in netplan.io package in Ubuntu:
  Fix Released

Bug description:
  netplan 0.35 would include an additional command:

   netplan try

  This would be used to allow users to automatically attempt to apply
  any config that can be safely programmatically revert in the case of
  failure, and presenting the user with a prompt to acknowledge the
  changes. The prompt is intended as a way to ensure the user still has
  access to the system when the settings are applied. In the event the
  user can't approve the changes, they are backed out after a timeout
  (120 seconds by default to give the network time to converge).

  Settings that can't be backed out are limited to custom bridge and
  bond settings that tweak behavior of these devices, since networkd
  does not necessarily update these settings when bond devices are
  changed (only when they are being created).

  'netplan try' is already available as a separate tree in git:
  https://github.com/CanonicalLtd/netplan/pull/15/files

  This FFE is to make sure the community is aware of these changes so
  late in the cycle, and to ensure those are acceptable to land right
  now, being leaf changes, fully covered by unit tests and autopkgtests
  (along with manual testing). Only users consciously making the
  decision to use the command would run into this code path.

  The changes are limited to some terminal mangling to allow for the
  prompt and timeout; everything else is handled directly in the
  existing 'netplan apply' code with minimal change to allow this code
  to be executed from another "command".

  This FFE request seeks pre-approval before merging the "try-command"
  branch that incldues this new feature into netplan master to proceed
  with the release of netplan 0.35.
