# Questions — v11 (current round)

New round opened by the 09-04 night grind (monitoring wiring t/335 EXECUTED;
apt-satellite lane LIVE; CA/ACME pilot done). Two gating questions for the
next phase. One-line answers fine. (v10 + history: archive/questions/)

## CA/ACME phase B (t/327 design)

**Q1 (DNS-01 for the fleet ACME).** The prod ACME endpoint on tsys-ca (phase
B) needs to validate knel.net identifiers. Recommended: **DNS-01 via
Technitium** — may I generate a TSIG key scoped to `_acme-challenge.*`
updates and load it on tsys-dns (one config edit + git SoR sync), or prefer
HTTP-01 only for now?

**Q2 (step-ca go on tsys-ca).** Deploy the prod ACME container on the tsys-ca
VM (new container, intermediate signed by the existing fleet root, bound to
the Tailscale IP :8443) — approve to start, or pick a window?
