arch-chroot - enhanced chroot command

arch-chroot [options] chroot-dir [command]

arch-chroot wraps the chroot(1) command while ensuring that important functionality is available, e.g. mounting /dev/, /proc and other API filesystems, or exposing resolv.conf(5) to the chroot.

If command is unspecified, arch-chroot will launch /bin/bash.


The target chroot-dir should be a mountpoint. This ensures that tools such as pacman(8) or findmnt(8) have an accurate hierarchy of the mounted filesystems within the chroot. If your chroot target is not a mountpoint, you can bind mount the directory on itself to make it a mountpoint, i.e.:

mount --bind /your/chroot /your/chroot

-u <user>[:group]
Specify non-root user and optional group to use.


Output syntax and command line options.
