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
+
* resolved:
- - CNAME resolver
- - cache
- - IDN
+ - IDN (?)
- DNSSEC
- LLMNR
- mDNS/DNS-SD
- DNS-SD service registration from socket units
- port sd-resolve to direct bus calls
- nss module: fallback to glibc dns modules if resolved cannot be contacted
+ - edns0 + dname
+ - cname on PTR (?)
+ - negative caching
* Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
* register catalog database signature as file magic
+* zsh shell completion: <command> <verb> -<TAB> should complete options, but currently
+ does not
+
Regularly:
* look for close() vs. close_nointr() vs. close_nointr_nofail()
