Files in /etc/sudoers.d/ must have strict permissions (typically 0440 or 0400) and be owned by root:root. If a file has more permissive permissions (such as 0644, which is the default when created via redirection with a standard umask), sudo and sudo-rs will ignore the file or fail with a permission error. To ensure the passwordless sudo rule is honored, explicitly set the file permissions to 0440.

RUN echo "%sudo ALL=(ALL) NOPASSWD: ALL" > /etc/sudoers.d/90-toolbx-nopasswd && \
    chmod 0440 /etc/sudoers.d/90-toolbx-nopasswd


# Enable the use of p11-kit-client.so to access CA certificates from the host
RUN mkdir --parents /etc/pkcs11/modules
