Hi, @Gabe: Thanks - that gives me some clarity. You are probably right about Android being unhappy about my device.
I used "mount -o loop /system/sdcard.img /mnt/sdcard" in my rcS file, where sdcard.img has been created using the Android SDK utility. The only guesses I can make about why this doesn't work is lack of root permission while executing the rcS or that Android's mount doesn't support mounting something that is not a block device. For now, I have shifted the mount command to init.rc instead. I would be grateful if someone more Android savvy could help me with the right way to do this.
