It is observed that for statically-compiled drbdadm, the working directory is /usr/local, therefore we device a temporary fix for the problem of drbadm no finding /usr/local/etc and /usr/local/var

   for i in etc var; do 
      mv -vf /usr-local/$i /usr-local/$i.bak
      ln -svf /$i /usr-local/$i
   done
