I actually started with RPi’s. The first one, a used Pi 4b, is dedicated only to HomeAssistant. I don’t tinker with it anymore because it does what I want and I don’t want unexpected downtime when I have to use the bathroom or use the lights in my room.
I bought a used Pi5 with the intention of upgrading later. In life I am quite minimal and find a joy in using what little tools and material I have to create something new. That seems to hold true to technology and scripting too. The RPi5 with an old USB3 HDD is actually way more power than I can currently use and can imagine using for a long time. The extra room to work is convenient though.
I’ll have a look into some of the places you suggested, those seem like the places to draw good inspiration from, thank you.
I have two systems that sort of work together.
The first system involves a bunch of text files for each task. OS installation, basic post OS installation tasks and a file for each program I add (like UFW, apparmor, ddclient, docker and so on). They basically look like scripts with comments. If I want to I can just copy/paste everything into a terminal and reach a a specific state that I want to be at.
The second system is a sort of “skeleton” file tree that only contains all the files that I have added or modified.
Here's an example of what my server skeleton file tree looks like
. ├── etc │ ├── crontabs │ │ └── root │ ├── ddclient │ │ └── ddclient.conf │ ├── doas.d │ │ └── doas.conf │ ├── fail2ban │ │ ├── filter.d │ │ │ └── alpine-sshd-key.conf │ │ └── jail.d │ │ └── alpine-ssh.conf │ ├── modprobe.d │ │ ├── backlist-extra.conf │ │ └── disable-filesystems.conf │ ├── network │ │ └── interfaces │ ├── periodic │ │ └── 1min │ │ └── dynamic-motd │ ├── profile.d │ │ └── profile.sh │ ├── ssh │ │ └── sshd_config │ ├── wpa_supplicant │ │ └── wpa_supplicant.conf │ ├── fstab │ ├── nanorc │ ├── profile │ └── sysctl.conf ├── home │ └── pi-user │ ├── .config │ │ └── ash │ │ ├── ashrc │ │ └── profile │ ├── .ssh │ │ └── authorized_keys │ ├── .sync │ │ ├── file-system-backup │ │ │ ├── .sync-server-fs_01_root │ │ │ └── .sync-server-fs_02_boot │ │ └── .sync-caddy_certs_backup │ ├── .nanorc │ └── .tmux.conf ├── root │ ├── .config │ │ └── mc │ │ └── ini │ ├── .local │ │ └── share │ │ └── mc │ │ └── history -> /dev/null │ ├── .ssh │ │ └── authorized_keys │ ├── scripts │ │ ├── automated-backup │ │ └── maintenance │ ├── .ash_history -> /dev/null │ └── .nanorc ├── srv │ ├── caddy │ │ ├── Caddyfile │ │ ├── Dockerfile │ │ └── docker-compose.yml │ └── kiwix │ └── docker-compose.yml └── usr └── sbin ├── containers-down ├── containers-up ├── emountman ├── fs-backup-quick └── rtransferThis is useful to me because I can keep track of every change I make. I even have it set up so I can use
rsyncto quickly chuck all the files into place after a fresh install or after adding/modifying files.I also created and maintain a “quick install” guide so I can install a fresh OS,
rsyncall the modified files from my skeleton file tree into place, then run through all the commands in my quick install guide to get myself back to the same state in a minimal amount of time.
