@ed, I just finished the backport to Eoan it was straightforward, I'll finish tests tomorrow with HA related software and networkd enabled HA clusters. After that I'll give you a better estimation about Disco and Bionic.
This is the total size of changes (systemd-networkd-tests.py is not so great to backport, will review that): $ cat *.patch | diffstat man/systemd.network.xml | 27 +- src/network/networkd-dhcp4.c | 8 src/network/networkd-link.c | 57 +++++- src/network/networkd-link.h | 2 src/network/networkd-manager.c | 2 src/network/networkd-network-gperf.gperf | 3 src/network/networkd-network.c | 44 ++++ src/network/networkd-network.h | 26 ++ test/fuzz/fuzz-network-parser/directives.network | 1 test/test-network/conf/24-keep-configuration-static.network | 5 test/test-network/conf/dhcp-client-keep-configuration-dhcp-on-stop.network | 4 test/test-network/conf/dhcp-client-keep-configuration-dhcp.network | 7 test/test-network/systemd-networkd-tests.py | 94 +++++++++- 13 files changed, 235 insertions(+), 45 deletions(-) Good thing is that the logic is not drastically changed for this feature to exist. Sorry for the delay here, because of freeze we were running to close out some urgent issues for Eoan. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1815101 Title: [master] Restarting systemd-networkd breaks keepalived, heartbeat, corosync, pacemaker (interface aliases are restarted) Status in Keepalived Charm: New Status in netplan: Confirmed Status in heartbeat package in Ubuntu: Triaged Status in keepalived package in Ubuntu: In Progress Status in systemd package in Ubuntu: In Progress Status in heartbeat source package in Bionic: Triaged Status in keepalived source package in Bionic: Confirmed Status in systemd source package in Bionic: Confirmed Status in heartbeat source package in Disco: Triaged Status in keepalived source package in Disco: Confirmed Status in systemd source package in Disco: Confirmed Status in heartbeat source package in Eoan: Triaged Status in keepalived source package in Eoan: In Progress Status in systemd source package in Eoan: In Progress Bug description: Configure netplan for interfaces, for example (a working config with IP addresses obfuscated) network: ethernets: eth0: addresses: [192.168.0.5/24] dhcp4: false nameservers: search: [blah.com, other.blah.com, hq.blah.com, cust.blah.com, phone.blah.com] addresses: [10.22.11.1] eth2: addresses: -
