This is a very known problem with the RPI that reboots too often it damages the SD cards. The last batch of 30 RPi's I've gotten in the last 6 months at least 10 have this problem. The fix to keep it going is to add boot_delay=1 to the config.txt, til it blows completely. This is common, or I just have bad RPi Karma. either way adding boot_delay=1 to your push will solve lots of problems people are having with them, and will not hurt people without it.
Downloaded from setup.hashfast.com image. Very different from what I had been given with the delivery 2 days ago it was a stock minepeon install. Getting the updates now.
But you guys are updating the /boot/config.txt which is removing the boot_delay=1 that allows this raspberry pi to boot without hanging at the Rainbow screen everytime a patch comes in. Also if I needed to allow it to boot without HDMI to come back later to check on it, I can't turn that on, so either stop that update or update the config lines only you are trying to push please

It should not hang at the rainbow screen. We now test every RPI that gets sent out, although there were some initially that didn't get tested. If you restore the SD to the HashFast image, initially it's not set up for forced HDMI, but we update that in the first few updates. Once you are at the current version, it should NOT hang on reboot, and HDMI should be on regardless of whether you started with a monitor connected. If this isn't happening for you, I suggest you try burning to a new fresh SD card. I've definitely seen the Pi hate on some SD cards!
Sorry for overwriting your configs, we are trying to make it easiest and most reliable for users that aren't very familiar with Linux, so it "just works" as well as possible. It really sounds like somethings wrong on your system, as the current loads never hang.
