Install the distro
Set up Ubuntu or Centos or some small embedded whateverism...
(Optional) Change the IP
If this is a VM clone, CHANGE YOUR IP NOW before you tear your hair out.
(Optional) Set up hostname
If you've cloned a VM, or you are using any "lite" OS that doesn't have an installer, you'll need to set your hostname to something unique, as a first step:
sudo emacs /etc/hostname && sudo hostname newname # use hostname cmd to set it right away # NOTE that systemd can also be used: sudo hostnamectl set-hostname newname # /etc/hosts changes should not be needed, if hostnames are properly configured (dnsmasq DNS -or- work DNS will provide resolution)
(Optional) Set up user m
"Lite" OS installs will not add a user for you, so if you don't have user m, add user m now.
(Optional) Limit system log size
Prevent endless system logging here.
Set up IP
On home lan, bitpost dnsmasq doles out the ips based on MAC:
hostname # make note ip address # make note of MAC - there may be more than one (eg: wired and wifi) [bitpost#] emacs config/etc/dnsmasq.d/mdm_lan_dnsmasq.conf && sudo service dnsmasq restart # reacquire IP on new box
Copy ssh keys
sudo apt install openssh-server # if needed (usually) ssh newbox # via password # 2022 keys mkdir -p .ssh/2022 [bitpost#] scp -r .ssh/2022/id_ed25519* newguy:.ssh/2022/ cd .ssh && ln -s 2022/id_ed25519 . && cat 2022/id_ed25519.pub >> authorized_keys
It's time to deprecate this one...
# 2018 keys mkdir -p .ssh/2018 [bitpost#] scp -r .ssh/2018/id_rsa* newguy:.ssh/2018/ cd .ssh && ln -s 2018/id_rsa . && cat 2018/id_rsa.pub >> authorized_keys
Install basic tools
sudo apt update && sudo apt upgrade -y && sudo apt autoremove -y sudo apt install git curl emacs-nox # ubuntu server sudo apt install git curl emacs # ubuntu desktop sudo yum install git curl emacs-nox # centos
Set up scripts
cd && mkdir development && cd development git clone morosoph:development/scripts.git ./scripts/setup_linux.sh [desktop|nodesk] # to continue bootstrapping
That's it, get on with your life.
