** Description changed: For snappy (at first at least) we need to provide netplan in xenial, as for the first snappy GA release we must not use any PPAs any more. netplan's NetworkManager backend depends on two patches to read configuration and connections from /run/NetworkManager/. These will need to be backported for full netplan support; but they are not required for snappy as this will use a snapped NM. However, this will need a temporary hack (https://code.launchpad.net/%7Emorphis/netplan/+git/netplan/+merge/306607) until snaps can actually properly support OS components like NetworkManager. PATCHES: https://git.launchpad.net/~network-manager/network-manager/+git/ubuntu/commit/?h=xenial&id=6dcdb85 https://anonscm.debian.org/cgit/pkg-systemd/systemd.git/commit/?h=ubuntu-xenial&id=4e9c52b0bb REGRESSION POTENTIAL: netplan: The risk for existing installations is practically zero as nplan does not exist in xenial yet and thus will not be pulled in during upgrades. - NetworkManager: Nothing in xenial expects/uses /run/NetworkManager/ and as it's an ephemeral tmpfs there is no risk of existing files there. If the patches are broken it could in theory happen that NetworkManager also does not properly read files from /etc/NetworkManager/ any more, so the -proposed package must verify that existing connections still work. - systemd: This does change behavior of networkd on restart, but the previous behaviour was arguably buggy. networkd is not being used by default or advertised in Ubuntu 16.04, so this will not affect the vast majority of installations. + + NetworkManager: Nothing in xenial expects/uses /run/NetworkManager/ and + as it's an ephemeral tmpfs there is no risk of existing files there.

Run "NetworkManager --print-config" again and verify that the output is the same as in step 1. 4. netplan has a very comprehensive integration test suite run as autopkgtest, which covers NetworkManager (including the /run patches) and network. Confirm that it succeeds.
