Thanks again for the info above. This is the kind of info that I understand but which seems to be missing from my f9 bible. Linux device names are quite different from device names in OpenBSD which I had been using for several years before I started using Linux (Fedora 9 and Suse 11). -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
