That's true in the case of generic OP. But as a list regular I'm
acquainted with Stephen, so I find this scenario unlikely.

And by doing *this* you're risking breaking systemd and the overall
boot process.
Yep, the thing's written that way - it *expects* (some can say 'forces')
you to have IPv6.
Hence this BSD-style "safe hack". Do not touch "base system" (systemd in
this case), but implement assorted kludges around it.
