The secret store's pki root issues every hive's gateway leaf and the
swarm's service names, so the root swarm-ca.service generated on the
host anchors nothing and its key is a secret outside the store.
- swarm-ca.nix is gone: swarm-ca.service, root.pem and root-key.pem,
and the swarm.ca.{autoConfigure,stateDir,validityDays} options. A
definition of any of them fails evaluation with a removal message
(swarm-ca-removed.nix), and a tmpfiles rule deletes /var/lib/swarm-ca
on every host. singleHostSwarm no longer sets a swarm.* option.
- hive-tls-ca drops the $root slot: trust-bundle.pem holds the store's
pki root and a hive CA's public ca.pem/ca-previous.pem only.
- hivectl peer-config no longer prints the scp line for the swarm root;
the store's pki root is the one step.
- The gateway's cert import no longer stands a hive leaf or a throwaway
in for a missing swarm-services leaf where it Requires= the issuing
unit: it fails, naming swarm-services-cert.service. The stand-in stays
where the gateway does not wait (no swarm name, or the store's UI
only, whose passthrough must start with the store sealed).
Comments and docs that named swarm-ca.nix, swarm.ca.* or the host root
now name the store's pki root.
