Hi, What is the difference between chroot & pivot_root.
As far as I know, chroot changes only the effective root for one newly started process and all the child processes it will start in the future, leaving all other processes unaffected, while pivot_root changes the root for the entire system, killing all other processes.
In the context of LXC, the pivot_root is done after switching into a private filesystem namespace (CLONE_NEWNS), so only the process doing the pivot and its children are affected, not the system as a whole.
