GOST If using a chrooted instance of BIND, the OpenSSL engines need to be accessible from within the chroot. If BIND is chrooted in /var/named, this can be achieved by either copying content of /usr/local/lib/engines into /var/named/usr/local/lib/engines, or by creating that directory and adding this line to /etc/fstab: /usr/local/lib/engines /var/named/usr/local/lib/engines nullfs ro 0 0
