When I read that line, I assumed that replacing a NIC in the same slot
would give rise to the same enpXsY numbers which would satisfy the
user alluded to earlier when I wrote 'You can find threads here
complaining loud and long about udev's persistent-net rules, one of
the preceding methods "foisted" on us by Debian.' With the latter, the
NICs new MAC would result in a new entry in persistent-net and a name
change to eth(N+1):.

I don't think I have the hardware to try this out; my only loose NICs
are identical twins.
