Hi Barry - You need to understand a core feature of Qubes - the use of Templates to back individual qubes. There is a good explanation here: www.qubes-os.org/doc/getting-started So you can make a permanent change by altering the Template on which your sys-net is based. It's also possible to make individual changes by putting them in to /rw/config/rc.local in the qube - Look here: www.qubes-os.org/doc/config-files/ Remember to chmod +x rc.local if you want the changes to take effect on boot. There is another mechanism - the use of bind-dirs to have a persistent config file in a Template-based qube. Again, that's covered inn the docs. cheers unman -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
