I downloaded all files, created an iso and noticed it's crap.
gfxboot starts but instead of back.jpg I just get a black background.
I didn't check the pre-created isos but the bootlogo from the above
mentioned isolinux directory is incomplete and does not contain all
required files. So I grabbed mageia-gfxboot-theme-4.5.6.9-1.mga6.src.rpm,
corrected IN_CPIO_INSTALL in the Makefile and created a proper bootlogo
file with size of ~953k instead of ~337k. With that file I get a proper
background and can't reproduce the original issue.
