+- `services.netdata` offers a `deadlineBeforeStopSec` option which enable users who have netdata instance that takes time to initialize to not have systemd kill them for no reason.

 - `services.dhcpcd` service now don't solicit or accept IPv6 Router Advertisements on interfaces that use static IPv6 addresses.
   If network uses both IPv6 Unique local addresses (ULA) and global IPv6 address auto-configuration with SLAAC, must add the parameter `networking.dhcpcd.IPv6rs = true;`.
