Mount the hddimg and rootfs.img as read-only when creating the bootable image on the medium. Otherwise, the md5 checksum values of the hddimg will be altered. As this changed checksum value might cause issue for users whom would reuse the hddimg.

Hooking up a serial console is a "developer mode", the chances are pretty good developers are interested in watching the kernel boot log on the console so they can spot any problems or diagnose any failed boots (e.g. can't find root fs).

If it is passed only the image parameter, it will show some interactive options to help to conclude the script. With this patch it will detect devices available in the machine, asking to choose what it is wanted to be flashed. it will suggest the target device. If it is a SD card the suggestion is /dev/mmcblk0. If it is a pendrive it will suggest to use /dev/sda.

If cleanup() is called early on, as happens when the device isn't writeable, then none of the mount point variables are set; thus the script was calling grep with only one argument and appeared to hang since it was waiting for input on stdin.

This avoids parted showing prompts and thus effectively hanging the script in in the case of initially malformed disks. Signed-off-by: Paul Eggleton <paul.eggleton@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
Add basic signal handling to unmount and remove any temporary files. Correct a quoting issue with the die() function caught testing signal handling. Fix a minor typo in "formatting" output.

The current script intends to redirect stderr to stdout, but instead redirects to a file named 1. No doubt a regex replace error. Replace all instances of 2>1 with 2>&1. Signed-off-by: Darren Hart <dvhart@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
My previous patch adding gummiboot support was missing the line to remove the initrd line from the boot config. This was an oversight in copying over the grub setup to gummiboot.
