NAME
       chroot -	change root directory for a command

SYNOPSIS
       newroot command

DESCRIPTION
       The  command  executes command relative to the newroot.	The meaning of
       any initial slashes in path names is changed for	command	and any	of its
       children	 to  newroot.	Furthermore,  the initial working directory is
       newroot.

       Note that command suffixes that affect input or output for the  command
       use the original	root, not the new root.	 For example, the command:

       locates file relative to	the original root, not the new one.

       The command variable includes both the command name and any arguments.

       The new root path name is always	relative to the	current	root.  Even if
       a is currently in effect, the newroot argument is relative to the  cur-
       rent root of the	running	process.

       This command is restricted to users with	appropriate privileges.

EXTERNAL INFLUENCES
   International Code Set Support
       Single- and multibyte character code sets are supported.

WARNINGS
       command cannot be in a shell script.

       Exercise	 extreme  caution  when	 referring to special files in the new
       root file system.

       does not	search the environment variable	for the	location  of  command,
       so the absolute path name of command must be given.

       When  using to establish	a new environment, all absolute	path name ref-
       erences to the file system are lost, rendering shared  libraries	 inac-
       cessible.   If  continued access	to shared libraries is needed for cor-
       rect operation, the shared libraries and	the dynamic loader  be	copied
       into the	new root environment.
