While waiting for the PR containing the fix for this to be merged, it is possible to recreate this functionality using your own tagged literal e.g. #host instead of #hostname:

e.g. Add this to a namespace before reading in configuration file:

(defmethod aero.alpha.core/eval-tagged-literal 'host
  [tl {:keys [hostname] :as opts} env ks]
  (aero.alpha.core/expand-case (or hostname (System/getenv "HOSTNAME"))
               tl opts env ks))
