   4 Subject: [PATCH] configure.ac: allow disabling registry downloads
   5
   6 Some environments require reproducible builds. Since the IANA PEN
   7 registry is constantly updating and there is no snapshot available,
   8 installing ipmitool via `make install` is not reproducible.
   9
  10 Provide a configure mechanism to disable the registry download/install..
