The `s6-chroot` program

s6-chroot executes a program in a chroot jail.

Interface

     s6-chroot newroot prog...

s6-chroot sets the root filesystem for the current process to newroot, which must be an existing directory.
s6-chroot changes directory to this new root, and executes prog with its arguments. prog is searched under the new root.
s6-chroot's parent process is unaffected by the root change.
