# Install FFHO internal CA into Debian CA certificate mangling mechanism so
# libraries (read: openssl) can use the CA cert when validating internal
# service certificates. By installing the cert into the local ca-certificates
# directory and calling update-ca-certificates two symlinks will be installed
# into /etc/ssl/certs which will both point to the crt file:
#  * ffho-cacert.pem
#  * <cn-hash>.pem
# The latter is use by openssl for validation.
