Sets up ZFS replication. Syncoid modules handles configuration for both
the remote and the target but I'm thinking I should split this up in the
future.
Made a separate ACME module to handle requesting certs from multiple
machines. Right now, the module only supports exactly one wildcard cert.
It might make sense to have cache.kilonull.com use a cert specific to
its subdomain rather than also requesting a wildcard cert (or maybe the
nginx on its host shouldn't care about TLS and it should be node's
responsibility).
