After reinstalling Linux you usually need to install packages, set up SSH, configure a firewall, and install apps. This repo automates all of that in one go.

It is a personal toolkit — a bootstrap script, a unified pos CLI for everyday tasks, optional app installers, and self-hosted services via ScaleTail + Tailscale.

What you get:

25+ system packages installed automatically
The pos CLI: network, Docker, media, system, SSH, communication (Telegram), and vbox tools
Wi-Fi hotspot tools (create_ap, wihotspot-gui) via pos network hotspot
15 optional desktop apps (VS Code, Brave, OBS, Tailscale, …) — pick what you want
119+ self-hosted services with Tailscale access (Jellyfin, Home Assistant, …)
systemd services for SSH agent and boot-time automation
Everything lands in /usr/local/bin/ — you can delete the repo after install

Quick Start

git clone https://gitea.skink-platy.ts.net/admin/Linux_post_install.git
cd Linux_post_install
./install.sh              # core: packages + CLI + services + ScaleTail
./install.sh --feature    # also install features/ scripts (asks before overwriting)
./install.sh --apps       # also install optional desktop apps (interactive)
