This is done with an overlay. The base file system is readonly. If you
aren't using a disk based overlay (for USB devices), you'll be limited to
whatever is used for the ramfs overlay. I don't know exactly how that is
sized, but it is probably some minimum and a fraction of your ram. So it
doesn't seem surprising that you get the same limit even with different sizes
for the image saved on the cd, dvd or usb device.
