In Fedora, the consolidated system-wide trust store is located in the `/etc/pki/ca-trust/` and `/usr/share/pki/ca-trust-source/` directories. The trust settings in `/usr/share/pki/ca-trust-source/` are processed with lower priority than settings in `/etc/pki/ca-trust/`.
NOTE: In a hierarchical cryptographic system, a trust anchor is an authoritative entity which is assumed to be trustworthy. For example, in X.509 architecture, a root certificate is a trust anchor from which a chain of trust is derived. The trust anchor must be put in the possession of the trusting party beforehand to make path validation possible.
