# The eMudhra intermediate CAs' private keys leaked in October 2026, and they chain to these two roots.
# OpenSSL checks no revocation, so Ruby trusts whatever they sign until the roots leave the bundle.
# ca-certificates is named in an apt-get install above, so a rebuild takes the distro's fixed package
# rather than the one frozen into the base image. Fail the build if either root is still installed.
