Thanks for the suggestion, but I still don't know how to proceed.
I assume that the absence of the line above + this line

  Dec 31 19:00:29 localhost dhcpcd[1346]:
    enp1s0: adding route to 169.254.0.0/16

results in the desktop machine killing the Dhcpcd process :

  # PP : 'ioff', remove conn'n
  dhcpcd[11404]: sending signal ARLM to pid 997
  dhcpcd[11404]: waiting for pid 997 to exit
  dhcpcd[997]: received signal ALRM from PID 11404, releasing
  dhcpcd[997]: enp5s0: removing interface
  dhcpcd[997]: enp5s0: releasing lease of 192.168.1.2
  dhcpcd[997]: enp5s0: deleting route to 192.168.1.0/24
  dhcpcd[997]: enp5s0: deleting default route via 192.168.1.1
  dhcpcd[997]: exited

which then has to be restarted via 'dhcpcd' after replugging the conn'n.

However, even after searching thro'  /etc  again, Googling etc,
AFAICS there's no difference in config files between the  2  machines.
So how do I "enable IPv4LL' (smile) ?
