I start the agent by hand execution of the script only when I intend to use it. The script reads encrypted keys from removable media, which is usually not present. > >> I am reminded of the air conditioning in our family cars. I have a >> 1999 Camry.

My suggestion is that by default, it be disabled. It might also be added to the install dialog (hopefully in terms that most reasonably well educated users could understand without web-search, which presently is the case for only a minority of the options). To whom do I present my suggestion, or have I just done it? :) Thanks again, Mike. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
