But that is for checkroot.sh , isn't it? I'm talking about non-root devices for checkfs.sh

About the "your proposed solution will only work for some machines, and slow down a lot of others" part, I think that the last patch I send doesn't slow any machines at all excepting machines expressely configured to do so.

About event based boot, I hope we will have it in the (near) future, but I'm trying to give a solution for today's systems.

Thanks for your time :)
