Available implementations at common/chroot-style/*.sh. Each .sh script there implements a chroot style to be able to chroot and bind mount with multiple utilities. The current supported list: - uunshare (uses xbps-uunshare(8)) - uchroot (uses xbps-uchroot(8)) - proot (uses proot, see http://proot.me) The XBPS_CHROOT_CMD can be set in etc/conf to use a specific implementation, and XBPS_CHROOT_CMD_ARGS to pass in additional arguments to the cmd.
