/proc/4/task/4/root/etc/pki/ca-trust/extracted
This explorer reads the filesystem of the server it runs on, so /workspace/user isn't present here. Browsing and the terminal still work against this server's own disk from /.
This directory /etc/pki/ca-trust/extracted/ contains CA certificate bundle files which are automatically created. If your application isn't able to load the PKCS#11 module p11-kit-trust.so,then you can use these files in your application to load a list of globalroot CA certificates. Please never manually edit the files stored in this directory,because your changes will be lost and the files automatically overwritten,each time the update-ca-trust command gets executed. Please refer to the update-ca-trust(8) manual page for additional information.
