Static IP configuration does not work on raspbian

[f34rdotcom]

After setting a static ip address multiple lines of configuration are written to /etc/network/interfaces file but the /etc/dhcpcd.conf is not touched on raspbian. This results in no change in network configuration.

This is what is needed at the end of /etc/dhcpcd.conf
interface eth0
static ip_address=1.2.3.4/24
static routers=1.2.3.4
static domain_name_servers=1.2.3.4

This is frustrating as clearly Raspbian and other Debian linux derivatives are no longer using the /etc/network/interfaces file to configure static IPs rather they are using the /etc/dhcpcd.conf file but the WebApp is definitely trying to edit the former interfaces file. I am rather surprised that this has been reported a year ago and yet is still not resolved.

I wish they would simply add the ability to edit this file on a fat partition like they did with wpa_supplicant.conf on the root partition.

From https://www.raspberrypi.org/blog/another-update-raspbian/
"If a wpa_supplicant.conf file is placed into the /boot/ directory, this will be moved to the /etc/wpa_supplicant/ directory the next time the system is booted, overwriting the network settings; this allows a Wifi configuration to be preloaded onto a card from a Windows or other machine that can only see the boot partition."

TODO: Switch to using nmcli to set static or dynamic ip and other network settings.
