new tls-cert-store and cert-bundle methods

Hello,

Now that we have system tls-cert-store, if one needs to reference
a tls-cert-bundle like provided by ca_root_nss, do we need
to concatenate all of the certs listed in /usr/share/certs/trusted
into, for example cert.pem then symlink /etc/ssl/cert.pem to
that concatenated file?

thanks in advance for any help/pointers/links
