@AppLee Now I see, said the blind man! I could not figure out why I couldn't write to the filesystem as root and sudo didn't work with the phone PIN. It's read-only because the entire filesystem is laid down during the porting process and thus only modified by the developers and then included in the port by the porters.
I'll get back to learning the porting process and waiting for the FP5 to go on sale! LOL. Thank you and I hope I'm not stating the obvious, but this is definitely helping me and hopefully others who get involved and read these forums.
