>> Already possible I believe. I think there's a persistent overlay kernel command argument that you can point to use a file on your USB drive if you're booting from CD. I may be wrong on this though. > I research for that.. I looked for "kernel command". The only sources I found where this* and this*. Both doesn't mention "persistent overlay". *http://fedoraproject.org/wiki/Anaconda/Options *http://docs.fedoraproject.org/install-guide/f11/en-US/html/ap-admin-options.html Only for USB-Sticks "persistent overlay" is mentioned. *http://fedoraproject.org/wiki/How_to_create_and_use_Live_USB And I found another guy who asked for the same feature. *https://www.redhat.com/archives/fedora-livecd-list/2008-October/msg00009.html -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
