My first guess after my first cup of coffee is that all you have to do is edit the boot menu to change 'union=aufs' to 'union=overlay'. Set edit_boot_menu="yes" in etc/refractasnapshot.conf and the boot menu will open in a text editor before the iso is made.
And I guess what I have to do is either detect the kernel version and automatically edit the menu or make the menu easier for the user to configure. I've been thinking about adding a menu configurator something like this...
Present a checklist of boot options with defaults pre-checked.
Let the user change it or accept the default.
Generate a single boot entry.
Repeat until the user is tired of adding boot entries.
At some point, I'll drop support for older versions of software, but I don't want to do that now.
Anyway, please let me know if that works.
Edit: Or, we might have to wait for newer versions of live-boot, et. al.
https://lists.debian.org/debian-live/20 ... 00239.htmlOK, linux-image-3.18 and live-boot-5.0 are still in experimental. Tools will catch up.
Edit 2: forgot to say thanks for the alert. Thanks! Any help keeping up with all the changes is needed and appreciated.
