Nonsense? I think the lines illustrate the issue to the
experienced eye and in fact, it did, so that Pierre-Elliott
spotted the issue (I tell it in a second).

I don't know, surely not intentional. I just ran out of ideas.

Sure, except: Emacs or Vim, which is better?
(Just kidding :))

I had told I would use vim to edit the file... but I had been wrong!
The machine I SSH'd to in fact was not a machine, but rather
a container, and the network configured by the virtualisation
environment! That is what changes the IP. The container op
made an error in the IP and I was the unfortunate one just
arriving in time :)

[x] vim
[x] Proxmox (but I didn't know this)
