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.

The last time I saw pivot_root in practical use, it was as part of some multi-
staged boot-over-nfs process.
