Hello I finally made a pen drive with UNetbootin that can print etc. Because it is on a writable pen drive is it safe or not. If it can be written to I wonder. I left it like this for updates etc. I think it is a persistent drive? Also do I have to make a new one every once in awhile or b/c of updates can I just leave it as is. Lastly how do you activate the ufw? It may not be necessary but I feel better behind the firewall. Thank you very much Peter
