currently, i'm reading the chapter on sharing filesystems here:
http://user-mode-linux.sourceforge.net/old/UserModeLinux-HOWTO-7.html
and i have a few (again, fairly basic) questions about running UML
using COW to protect the root filesystem from modification.
first, is there any way to truly protect the root filesystem from
modification if i accidentally fire up a UML session against that root
filesystem and forget to use COW? as i read it, nothing stops me from
doing that and, if i absent-mindedly make changes to the root
filesystem at that time, i invalidate all my other COW-based UML
sessions based on that root FS, correct? so is there any way to stop
me from making that kind of mistake?
actually, that's my only question for now, more later.
