[dnsdist] dnsdist and Let's Encrypt (ACME)

[Stephane Bortzmeyer]

[I believe I've checked the available documentation, and found
nothing. Sorry, if I missed it.]

My dnsdist setup (DoT and DoH) uses a CAcert certificate and it works
fine. Now, I would like to move to Let's Encrypt but I do not see how
to make it work from dnsdist.

HTTP challenges? I don't think there is an ACME client in dnsdist.

DNS challenges? I don't really want to switch my zones to a dynamic
setup.

Is there an obvious solution I've missed?
