Coping with power loss
I'm configuring a Gentoo system on a Single Board PC (Atom), which will run headless and collect datas from sensors.
I will run where power is not always guaranteed. There may be intermittent power fails and brown-outs. I am worried that if there are too many fails, there is increased chance of it failing to boot due to corruption like a desktop OS.
I hear that the Raspberry Pi can be turned off without any problems. How do they achieve this? I would like to do the same thing.
Do I just need to use journaling? ext3? At the moment I have ext2 boot and ext3 root. Perhaps I should change boot to ext3 too and it will be ok?
I could make battery back-up for it, but I'd rather use Linux.
Thank you all.
