These scripts are seriously useful, have you thought about making them more widely available?
Yes, someday.
By coincidence, I'm giving a workshop session on "hacking the empeg" at OLS-2008 (Ottawa Linux Symposium) later this week. I basically picked that topic because I didn't have a better one at the time.
But something like this could be my ticket for next year, or perhaps some other conference.
The system shutdown is not 100% clean yet, though. It's safe, but it doesn't fully unmount everything as it should. I think another pivot_root (back to the underlying CF/disk) might be needed to correct it. Once I hack at that and get it working 100% correct, *then* I'll have something to give a workshop on.
Cheers
