Prior to version 4.3.0, the interpretation of the
--emake-reg-roots command-line option was that it would replace the
built-in default registry root setting. A side-effect of this
implementation was that the user could completely disable registry
mirroring by specifying
--emake-reg-roots="" (that is, an empty
However, the override behavior made it easy for users to unintentionally disable registry mirroring for the default locations when all they wanted was to also mirror some set of keys. This in turn made it possible for users to inadvertently “corrupt” the registry on the cluster by allowing modifications to bleed through to the real registry there.
