</ol>
{{Admon/important|Pathname for USB Stick|The procedure default mount location has been changed to refer to the usb device for in linux distributions prior to Fedora17 (egnewer than CentOS. So while we will get /media/usb-device-name). For Fedora17, the new device pathname is:<br /><b>in newer distributions you'll see /run/media/userloginid/usb-device-name</b> .<br /><br />Note: You can press the <b>tab</b> key to guess what the userloginname/usb-device-name is...}}

<ol>{{Admon/tip |Updating Fedora|<li value="15">The Fedora CentOS software is updated frequently to add features, fix bugs, and upgrade security. '''Perform a system update to get the latest versions of the packages installed in Fedora: Start the Firefox web browser, turn off popup window blocking (select ''Edit>Preferences'', then select the Content tab and uncheck the box to Block Popups), then login to SeneNET. Open a terminal and type <code>su</code> to start a shell as root. Enter the command <code>yum update</code>''' This will download and install all of the packages that have been updated since the installation DVD image was created. If you complete this command at Seneca it should run quite fast as Seneca College hosts a Fedora CentOS Repository mirror (a copy of all of the current fedora packages, on a local web server).}}</li></ol>
