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.
