remote kernel developing with arm soc board eval kit

Hello list, I've a soc board on my desk in the office and would like to know what is the best practice to do kernel development remotely with such a board. In the office I can plug in sd-cards or switch power off which I can't do if I'am not physically present. But I think with a tftp/nfs setup and ssh/minicom I can do something in that direction. So I would like to know how the real kernel developers build such a setup and how they handle kernel panics without driving back to office or call a collegue. Best regards, Oliver
