chroot is an operation on Unix and Unix-like operating systems that changes the apparent root directory for the current running process and its children. A program that is run in such a modified environment cannot name (and therefore normally cannot access) files outside the designated directory tree.

Crouton (ChromiumOS Universal Chroot Environment) is a set of scripts which allows Ubuntu, Debian, and Kali Linux systems to run parallel to a ChromeOS system. [1] Crouton works by using a chroot instead of dual-booting to allow a user to run desktop environments at the same time: ChromeOS and another environment of the user's choice.
On the LTSP server, a chroot environment is set up with a minimal Linux operating system and X environment.; Either: the computer will boot [3] from a local boot device (like a harddisk, CD-ROM or USB disk), where it loads a small Linux kernel from that device which initializes the system and all of the peripherals that it recognizes, or
Originally, LXC containers were not as secure as other OS-level virtualization methods such as OpenVZ: in Linux kernels before 3.8, the root user of the guest system could run arbitrary code on the host system with root privileges, just as they can in chroot jails. [9]
Also, because it uses a standard chroot'able file system for every node, it is extremely configurable and lends itself to custom environments very easily. While Warewulf was designed to be a high-performance computing (HPC) system, it is not an HPC system in itself.
The restricted shell is a Unix shell that restricts some of the capabilities available to an interactive user session, or to a shell script, running within it.It is intended to provide an additional layer of security, but is insufficient to allow execution of entirely untrusted software.
This does come with limitations as some emulators utilize PRoot which is a chroot like environment. [5] [6] Unlike terminal emulators that emulate the internal OS with/without any extension package support, it can install actual (for example) Ubuntu packages, as it does not rely too much on the Android system limitations. However, not all ...
