 Features:
 
+* libsystemd-network:
+  - I don't think there should be a client side object for dhcp
+    releases (probably not even a directory in /run for it)
+  - the order between ipv6 and ipv4 dns servers probably matters,
+    hence the current DNS apis won't suffice
+  - sd_network_get_ifindices() sounds redundant, rtnetlink can do that too

 * resolved:
   - IDN (?)
   - DNSSEC
