first setup steps

log in with your root ssh key

local> ssh -i ~/.ssh/root_key_rsa root@

set a root password

root@remote> passwd

install zsh and vim

root@remote> pkg install zsh
root@remote> pkg install vim-lite

create a new user

root@remote> adduser

adduser: INFO: Successfully added (johndoe) to the user database.
Add another user? (yes/no): no

enable group "wheel" for sudo:

root@remote> visudo
## Uncomment to allow members of group wheel to execute any command
%wheel ALL=(ALL) ALL

Transfer another ssh public key to the machine for the new user, move it to the right location and set the user / group accordingly

local> scp -i ~/.ssh/root_key_rsa _~/.ssh/
root@remote> mkdir /home/johndoe/.ssh
root@remote> mv ~/ /home/johndoe/.ssh/authorized_keys
root@remote> chown -R johndoe /home/johndoe/.ssh

Try to log in as new user on remote machine (and configure zsh)

local> ssh -i ~/.ssh/user_key_rsa johndoe@

Since there is now a user with sudo privileges, we don't need to login as root anymore. Every other config should be done with the new user and sudo:

local> ssh johndoe@
