arch-chroot is an enhanced chroot wrapper designed to simplify the Arch Linux installation and recovery process. Unlike plain chroot, it automatically mounts essential API filesystems (/proc, /sys, /dev, /dev/pts, and /run) before entering the chroot environment, and cleanly unmounts them upon exit.
This makes it significantly easier to perform system administration tasks on a mounted root filesystem, such as installing packages, configuring bootloaders, or repairing a broken system from a live environment. It can also run a single command and exit, or start an interactive shell as a specified user.
