Linux barebones quickstart

Install the distro

Set up Ubuntu or Centos or some small embedded whateverism...

Set up IP and hostname

Note that a fresh install of ubuntu will set the hostname. But if you've cloned a VM, for example, you'll need to change hostname:

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)

On home lan, dnsmasq doles out the ips based on MAC:

Add a new line to /etc/dnsmasq.conf with your MAC and an available IP.
Add your hostname and IP to hosts file.

Or, if this is a VM clone, CHANGE YOUR IP NOW before you tear your hair out.

Install git

sudo apt install git # ubuntu
sudo yum install git # centos

Copy ssh keys

mkdir -p .ssh/20##
bitpost# scp -r .ssh/20##/id_rsa* newguy:.ssh/20##/
cd .ssh && ln -s 20##/id_rsa .

Set up scripts

cd && mkdir development && cd development
git clone bitpost.com:development/scripts.git 
./scripts/setup_linux.sh # to continue bootstrapping

That's it, get on with your life.

MIGRATION IN PROGRESS: config distro machine migration

Start to revamp config from [machine]/[distro] to [distro]/[machine] to match scripts. It's not hard even though it's dangerous. You can do each machine separately from others. Get on it!

# DO THIS ALL IN ONE SESSION, do not log out
cd development/config
mkdir -p distro # prolly not needed
git mv machine/distro distro/machine
setup_stow.sh # repeat until it doesn't fail; check each failure to make sure it is a symlink, and simply rm them as you go

OLD

moving all this to setup_linux.sh and mh-setup-linux command...

cd && ln -s development/scripts scripts
mkdir scripts/[distro]/[new machine]
emacs -nw .bashrc 
# export PATH=$HOME/scripts/[distro]/[machine]:$HOME/development/scripts/[distro]/i3:$HOME/development/scripts/[distro]:$PATH

Set up ssh

# openssh-server defaults are ok but see /etc/ssh/sshd_config for details
cd ~/.ssh
scp [another-working-setup]:.ssh/authorized_keys .
scp [another-working-setup]:.ssh/id_rsa_3072_nopswd .
scp [another-working-setup]:.ssh/config .
ln -s id_rsa_3072_nopswd id_rsa
# also add any other private keys and run [chmod 400] on them

Set up config

cd ~/development
git clone bitpost.com:development/config.git 
cd config
mkdir -p [distro] && cd distro
cp -rp [existing machine] [new machine]
# EDIT IT ALL
# WARNING - EDIT ACTUAL SYSTEM FILES, NOT repo files, as those will get clobbered when you stow
# BACK EVERYTHING UP AS YOU GO until we get really good at this :-)
git add [new machine]
git commit -a -m "new machine" && git push
cd && ln -s /home/m/development/config/  optional:[gig]/  [distro]/[new machine] config
