The dnscrypt-proxy service relays regular DNS queries to
a DNSCrypt enabled upstream resolver.
The traffic between the client and the upstream resolver is
encrypted and authenticated, which may mitigate the risk of
MITM attacks and third-party snooping (assuming a trustworthy
upstream).
Though dnscrypt-proxy can run as a standalone DNS client,
the recommended setup is to use it as a forwarder for a
caching DNS client.
To use dnscrypt-proxy as a forwarder for dnsmasq, do
```nix
{
# ...
networking.nameservers = [ "127.0.0.1" ];
networking.dhcpcd.extraConfig = "nohook resolv.conf";
services.dnscrypt-proxy.enable = true;
services.dnscrypt-proxy.localAddress = "127.0.0.1";
services.dnscrypt-proxy.port = 40;
services.dnsmasq.enable = true;
services.dnsmasq.extraConfig = ''
no-resolv
server=127.0.0.1#40
listen-address=127.0.0.1
'';
# ...
}
```
It's not that difficult to define shares using standard samba config
file syntax, so why do we need the semi-configurable .defaultShare
option?
Also:
* It uses /home/smbd and I think /home should be reserved
for real human users.
* If enabled, it breaks the assumption that .extraConfig continues in
the [global] section.
Without .defaultShare there is no need for the "smbguest" user and group
either, mark them as unused.
* The module now has systemd config
* Add resolveLocalQueries option which sets up it as a dns server for
local host (including reasonable setup of resolvconf)
* Add "dnsmasq" user for running daemon
* Enabled dbus and dnssec support for the package

Additionally, remove the automatic initialization of the ipv6 forwarding
sysctl as this should be handled by the end user. This really should not
be an issue as most people running radvd are likely forwarding ipv6
packets.
This version of module has disabled socketActivation, because until
nixos upgrade systemd to at least 214, systemd does not support
SocketGroup. So socket is created with "root" group when
socketActivation enabled. Should be fixed as soon as systemd upgraded.
