Here's the problem. Now that we've gotten to the point you're listening.

Firstly: When someone makes an massive over-generalization such as "EVERY" developer is "playing with fire" by manipulating the BOOT SECTOR. This is very very bad, and implies something significantly worse than what you meant. It also makes anybody with a clue read your post and default you to "Idiot doesn't know what he's talking about" instead of actually trying to piece together the half-truth of what you're saying.

Secondly: Filling up the Root Filesystem is recoverable without a reflash if you have root! Should I say that again? No.. just read it a couple times for me. That's right; even if I run a simple dd if=/dev/zero of=/myimg nonstop until I completely fill up the root filesystem I can actually recover from that without ever reflashing the device! This is in NO WAY more dangerous than actually flashing new firmware! That actually does manipulate things such as the boot sector! This is why if you're going to install anything from Devel my recommendation is your first app be rootsh!

Thirdly: When you realize what you said != what you meant to say: CORRECT YOURSELF; don't continuously argue with several long standing members that have been dealing with this stuff every day as both a job and a hobby using the same wrong language. You'll get no where but look silly.

Now, I'm glad PR1.2 works for you. I'm glad that, for the most part, this firmware release is harmless. That still doesn't mean we should be advocating that everyone under the sun flash any and every possible firmware that gets posted on these forums. That is simply bad practice, and trying to "down" play the risks everyone took does nobody any good and could very well get someone a $500 actual brick that is completely irrecoverable.

Just look at the warnings on the non-proprietary meego:
Yes, you can actually completely damage your device by using unofficial, untested firmware!
