CHROOT(C) XENIX System V CHROOT(C)
Name
chroot - Changes root directory for command.
Syntax
chroot newroot command
Description
The given command is executed relative to the new root. The
meaning of any initial slashes (/) in pathnames is changed
for a command and any of its children to newroot.
Furthermore, the initial working directory is newroot.
Notice that:
chroot newroot command >x
creates the file x relative to the original root, not the
new one.
This command is restricted to the super-user.
The new root pathname is always relative to the current root
even if a chroot is currently in effect. The newroot
argument is relative to the current root of the running
process. Note that it is not possible to change directories
to what was formerly the parent of the new root directory;
i.e., the chroot command supports the new root as an
absolute root for the duration of the command. This means
that ``/..'' is always equivalent to ``/''.

Notes
Exercise extreme caution when referencing special files in
the new root file system.
command must be under newroot or command is reported:
command: not found
