SUDO
     -	 sudo is replaced by doas
     -	 add wheel group to the users that need root access
	       usermod -G wheel user
     -	 create the config
	       cp /etc/examples/doas.conf /etc/
     -	 modify config to not ask the password everytime you run doas
	       permit persist :wheel

BASH
   change shell from ksh to bash
	   chsh -s /usr/local/bin/bash
     for scripts change:
	   #!/bin/bash
     to
	   #!/usr/bin/env bash
     if it still shows error:
	   bad interpreter
     find the location of bash and use the resulting path instead
	   whereis bash

MOUNT ISO
     vnconfig $iso_file
      mount -t cd9660 /dev/vnd0a /path_to_iso_mount
