Ouya: blacklist boot partition to avoid brick

Thanks to Robert Yang's pmbootstrap patch, we can now avoid flashing anything to the boot partition of the Ouya. With this patch, the latest pmbootstrap will refuse to do so with:

ERROR: 'boot' partition is blacklisted from being flashed! See the Ouya device wiki page for more information.

Should recovery be blacklisted too? I think there are only two possible ways to install the pmOS boot.img for Ouya.

1. Boot into recovery. adb push the boot.img to /system/boot.img or /sdcard/altboot.img.
2. Flash boot.img to recovery.

In the second case we are pushing the users to manage restoring recovery themselves if need be. This could lead to mistakes such as inadvertently fastboot flashing boot. I was thinking it's safer just to avoid the dealing with fastboot flashing boot/recovery and encourage people to stick with the safest option only.

Good point! Updated to blacklist recovery too.

Hmm, shouldn't we blacklist those partitions for basically every device? We have no business there whatsoever right?

The isorec method requires writing to the recovery partition.

I don't think we need to blacklist recovery in general, because even if you overwrite it, you can always boot into the bootloader (usually fastboot) and flash something else to the recovery partition afterwards.

The Ouya is a special case, because once you overwrite boot, you can not overwrite it again. And overwriting recovery in the Ouya may lead them to overwrite boot by accident when restoring the recovery partition, as @ryang2678 explained above.
