Yeah, but compared with your hypothetical and with the old style Kung Fu
netcon servo practically broken within the grand systemd schema,

/etc/init.d/netconsole

netpoll: netconsole: local port 12345
netpoll: netconsole: local IPv4 address 0.0.0.0
netpoll: netconsole: interface 'enp1s2'
netpoll: netconsole: remote port 12345
netpoll: netconsole: remote IPv4 address 192.168.1.1
netpoll: netconsole: remote ethernet address 00:11:22:33:44:55
netpoll: netconsole: device enp1s2 not up yet, forcing it
netpoll: netconsole: no IP address for enp1s2, aborting
netconsole: cleaning up


Netconsole NG is simple as it can be, and most importantly works in all
conditions,

/usr/lib/systemd/system/netconsole.service

netpoll: netconsole: local port 12345
netpoll: netconsole: local IPv4 address 192.168.1.2
netpoll: netconsole: interface 'enp1s2'
netpoll: netconsole: remote port 12345
netpoll: netconsole: remote IPv4 address 192.168.1.1
netpoll: netconsole: remote ethernet address 00:11:22:33:44:55
console [netcon0] enabled
netconsole: network logging started

netpoll: netconsole: local port 12345
netpoll: netconsole: local IPv4 address 192.168.1.2
netpoll: netconsole: interface 'enp1s2'
netpoll: netconsole: remote port 12345
netpoll: netconsole: remote IPv4 address 192.168.1.1
netpoll: netconsole: remote ethernet address 00:11:22:33:44:55
netpoll: netconsole: device enp1s2 not up yet, forcing it
console [netcon0] enabled
netconsole: network logging started


Now you can pursue the beauty of design. :)
