glibc is going to make it available too. This locale enables UTF-8
mode by default, which appears appropriate for 2018.
+ * The "net.ipv4.conf.all.rp_filter" sysctl will now be set to 2 by
+ default. This effectively switches the RFC3704 Reverse Path filtering
+ from Strict mode to Loose mode. This is more appropriate for hosts
+ that have multiple links with routes to the same networks (e.g.
+ a client with a Wi-Fi and Ethernet both connected to the internet).
+
+ Consult the kernel documetnation for details on this sysctl:
+ https://www.kernel.org/doc/Documentation/networking/ip-sysctl.txt
