The first part of the sentence does not make much sense. In order to override the default TLS certificate location for VxHS backed storage, supply a valid path to the certificate directory. > +# This is used to authenticate the VxHS block device clients to the VxHS > +# server. > +# > +# If the provided path does not exist then the default_tls_x509_cert_dir > +# path will be used. > +# > +# VxHS block device clients expect the client certificate and key to be > +# present in the certificate directory along with the CA master certificate. > +# If using the default environment, default_tls_x509_verify must be configured. > +# The server key as well as secret UUID that would decrypt it is not used. What do you mean by: "UUID that would decrypt it"? Rest looks okay, but I need clarification on the above statemet.
