certutil: could not authenticate to token NSS FIPS 140-2 Certificate DB.: SEC_ERROR_IO: An I/O error occurred during security authorization.

systemd-importd runs as init_t

The systemd-importd service is using the NoNewPrivileges security flag in the systemd unit file. This blocks the SELinux domain transition from the init_t to systemd_importd_t domain. (BZ#1365944)

# chmod go-w /var/run/
