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

#!/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
