Do cleanup of user-created additional rules.
Of course it'd be much better to just use iptables-{save,restore} for
declarative management, but as it's still not there...
a) Some providers can update multiple domains - support that.
b) Make "zone" and "script" configurable. Some providers require these.
c) Instead of leaving the ddclient daemon running all the time, use a systemd
timer to kick it off.
d) Don't use a predefined user - run everything via DynamicUser
e) Add documentation
Currently broken on NixOS due to hardcoded modprobe binary path (see
bug #30756 from Oct 2017), no activity on a proposed fix for months.
As the protocol is terribly broken anyways, let's better remove it
completely, and not talk about anymore ;-)
Closes#30756.
Resolved the following conflicts (by carefully applying patches from the both
branches since the fork point):
pkgs/development/libraries/epoxy/default.nix
pkgs/development/libraries/gtk+/3.x.nix
pkgs/development/python-modules/asgiref/default.nix
pkgs/development/python-modules/daphne/default.nix
pkgs/os-specific/linux/systemd/default.nix
I determined which options got changed by executing the following
commands in the strongswan repository:
git diff -U20 5.6.0..5.6.1 src/swanctl/swanctl.opt
git diff -U20 5.6.0..5.6.1 conf
The strongswan-swanctl systemd service starts charon-systemd. This implements a IKE daemon
very similar to charon, but it's specifically designed for use with systemd. It uses the
systemd libraries for a native integration.
Instead of using starter and an ipsec.conf based configuration, the daemon is directly
managed by systemd and configured with the swanctl configuration backend.
See: https://wiki.strongswan.org/projects/strongswan/wiki/Charon-systemd
Note that the strongswan.conf and swantctl.conf configuration files are automatically
generated based on NixOS options under services.strongswan-swanctl.strongswan and
services.strongswan-swanctl.swanctl respectively.
