[Greg Chicares]

branch: master
commit 17016f421ffa88c6be4ca07fd9bbacfa29056f1d
Author: Gregory W. Chicares <address@hidden>
Commit: Gregory W. Chicares <address@hidden>

    Add instructions for creating a chroot
    
    The initial version of these instructions is copied from
      http://lists.nongnu.org/archive/html/lmi/2016-09/msg00000.html
    It is known to fail 'make check_concinnity'; soon it will not.
