** Description changed:
+ [impact]
+
+ ip addresses managed by keepalived are lost across networkd restarts
+
+ [test case]
+
+ see original description below
+
+ [regression potential]
+
+ this backports KeepConfiguration parameter, which adds some significant
+ complexity to networkd's configuration and behavior, which could lead to
+ regressions in correctly configuring the network at networkd start, or
+ incorrectly maintaining configuration at networkd restart, or losing
+ network state at networkd stop. Any regressions are most likely to
+ occur during networkd start, restart, or stop, and most likely to
+ involve missing or incorrect ip address(es).

Run 'netplan try' (didn't even make any changes to the configuration) and the
keepalived addresses disappear never to return, the affected interfaces have:
