I couldn't find a way, is there any? If not, I'd like to request such functionality. Preferrably selectable at mount time, via an argument to mount (or the `rootflags' kernel parameter). Something along the lines `rollbackto='. The desired effect is to set the indicated checkpoint as the latest one, so all subsequent changes to filesystem are discarded. What are your thoughts on that?
