Comment 6 for bug 1853914

I've been able to workaround these issues by manually editing the contents of the "custom-live-iso/preseed" folder. I was able to add my desired folder as well as make the scripts and binaries executable.

Only thing is that Cubic does not show the contents of the preseed folder in the GUI (it seems to stop listing files after it runs into the folder in alphabetical order), but that isn't an issue for me at this point.

In the future, it would be nice to be able to do all of this directly through Cubic though.
