Ruled by Captain Bob, 2026-11-07: "New root CA on the CI box. Valid
StarshipOS rather than snake oil intermediate."
- ci/pki/make-ca.sh makes the StarshipOS Root CA (its key stays on the CI
box) and the StarshipOS Capsule Signing intermediate it issues, and
stores the signing key as the secret CAPSULE_SIGN_KEY.
- The kernel finds the signing certificate by one name,
CAPSULE_SIGNING_CERT_NAME = pki:starshipos-intermediate.der. The
certificate itself lands once make-ca.sh has run; until then the
snakeoil intermediate is in the tree under its old name and the
capsules check as "no root key" (a warning, as "missing" was).
- mkcapsule refuses a signing key that is not that certificate's.
- SIGN_KEY has no default; acceptance, build, nightly and release set it
from the secret.
