R/chroot.R

In jeroen/unix: POSIX System Utilities

#' Change Root Dir
#' 
#' Changes the root directory of the calling process to that specified in path.  
#' This directory will be used for pathnames beginning with `/`.
#' **Only a privileged process (i.e. sudo) may call `chroot()`**.
#' 
#' This call changes an ingredient in the pathname resolution process
#' and does nothing else.  In particular, it is not intended to be used
#' for any kind of security purpose, neither to fully sandbox a process
#' nor to restrict filesystem system calls.
