How to get into chroot while keep Bash behavior settings, and important tools else, fully intact at once
If Bash is installed in the system you are chrooting into you can simply type # bash after entering the chroot shell and it will open a bash shell, the same applies for zsh, fish and so on. The bash-completion package can be useful, if not installed the behaviour can be a bit different.
You can also go directly to your preferred shell using artix-chroot, found in the artools-base package:
$ artix-chroot --help
usage: artix-chroot chroot-dir [command]
-h Print this help message
If 'command' is unspecified, artix-chroot will launch /bin/sh.
