Question about environment variables

[woody]

I've been trying everything I can to try to get my Pogoplug V2 to reboot successfully from a USB hard drive. Right now, I have to pull the power cord every time to get it to reboot. Also, recently, the Pogo failed to boot up after a power failure.

While I'm experimenting, I don't want to hose up my system so that it won't boot up at all. Is there a way to back up and restore some default environmental variables? Or else, is there a way that I can edit my USB drive in another PC to fix the environment variables, in case I break something?

Generally, the entire configuration is stored in /etc and your home directory (/root or /home/username)

Those are stored in the nand

Never mind. I figured out that I can boot back into the original "naked" Pogoplug firmware and reset the U-boot variables there. For some reason, I thought that the updated U-boot would now allow me to boot into the old Pogoplug environment, but obviously that's incorrect. Lots to learn about hacking these things!
