Why would you want to do that? One of the more popular reasons is to create a sandbox for either an application or a user. Once a new root is declared via chroot, any references that a user or application makes to ‘/’ will resolve to the new directory. This is a pretty effective way to restrict access to the real root and therefore the real file system. In fact, sometimes that act of chrooting is referred to a jailing or a chrooted shell is referred to as a jail shell.” Read more here: http://www.newlinuxuser.com/explain-what-is-chroot/ [...] [...] “The chroot command ‘changes the root’ to another location.

Example: chroot /home/jon will try to execute $SHELL, like /bin/bash, if no other options are given. This means /home/jon/bin/bash and it support files must exist. Run ldd /bin/bash to find out what shared libraries must exist. Also run info chroot on any linux system for a good example. The executables you want to use must be in the chroot directory.

Thanks, Jorge Hi, this explanation of chroot is quite useful, but, what if I issued the chroot command and now I want to change my / to the original place (referencing the / filesystem and anything above it at its original place), how can I perform this?
