Re: [ANN] US/North American Bitfury sales now open ***full prototype pics***
I've been using shutdown, but it reboots automaticly. so when it asks for a login i turn off the power supply. so far that hasn't hurt the SD card. 
If you use
Code:
shutdown -h now
it will not rebootjust use
poweroff
Dont forget sudo before shutdown commands.
sudo shutdown -h now --should work.
