From review: the store and broker passwords genesis makes were carried into
the controller through a world-readable file in /tmp, a bundle left at 0644 by
an earlier installer kept that mode while now holding them, a mesh raised by
the old installer would have been handed new passwords its servers do not have,
and the broker-admin action's marker did not depend on the value. Secrets now
stage in a 0700 directory owned by the controller's account; the bundle is
chmod'd; an existing store or broker volume with no credential file is refused
by name; the marker holds the password's fingerprint. Also: one install path
for the store, broker and vault, no error-string matching for the operator
key, and no unreachable fallback for the superuser.
