/etc/ssl
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/ssl) is provided as a courtesy attempt to providecompatibility with software which assumes its existence. It is not asupported or canonical location. Software which assumes and relies onthe existence and layout of this directory is making a wrong assumption(this directory is not any kind of 'standard', it is a configurationdetail of Debian and its derivatives) and should be improved. Nosoftware packaged in this distribution should use this directory. An attempt is made to make the layout of /etc/ssl/certs match thatprovided by Debian: it is an OpenSSL 'CApath'-style hashed directoryof individual certificate files, and also contains a certificate bundlefile named ca-certificates.crt, as Debian does. It also contains abundle named ca-bundle.crt, as this distribution has long providedsuch a file, and it is possible some software has come to expect itsexistence. /etc/ssl/certs itself and the bundle files are in fact symlinks tosome of the output of the 'update-ca-trust' script which forms a partof a system of consolidated CA certificates. Please refer to theupdate-ca-trust(8) manual page for additional information.
