Once the archive verifies, USB detection runs (so a stick plugged in while
the backup ran is found): mounted removable storage is auto-detected via
lsblk -J + a recursive jq filter (rm, mounted, type part|disk — JSON makes
spacey mountpoints safe), or BACKUP_USB_ROOT pins a fixed stick and skips
detection. None mounted → one re-scan prompt ('s' skips, EOF from cron
skips silently, rc stays 0); one stick → y/N confirm; several → numbered
pick (0 = skip). The copy lands in <usb>/backups/ (mkdir -p, chmod 600
best-effort — a vfat chmod failure warns, never fails the copy) and the
transfer is proven 100% by sha256 source-vs-copy before any success is
announced; a mismatch warns with both hashes, notifies 'USB copy FAILED',
and exits 1. The ERR trap is re-armed before the USB phase so a copy
failure no longer notifies 'Backup FAILED'. Docs: usage() Environment,
POS.md backup row, howto/system.md (USB section + env table + mismatch
troubleshooting), DEV.md system.env list. Stub suite
(/tmp/opencode/backup-test, HOME-isolated, sudo/gpg/lsblk/sender stubs,
corrupting-cp + vfat-chmod overrides, per-test lsblk JSON fixtures):
40/40 green.
Documentation
Everything in this folder is reference material for the Linux_post_install project. The root README is the short intro + quick start; this folder holds the detail.
| Document | What it covers |
|---|---|
| HOWTO.md | Hands-on guides per category (ai, network, docker, media, system, ssh, share, communication, entertainment): flags, recipes, config, troubleshooting |
| SCRIPTS.md | Core installer scripts: install.sh, preinstall.sh, postinstall.sh, lib/common.sh, lib/flags.sh, lib/entertainment-lib.sh, features/autostart.sh — purpose, how each works, configuration |
| POS.md | The pos CLI: dispatcher, every pos-* command, Docker Compose / ScaleTail config, legacy wrappers, flag CLIs |
| APPS.md | Optional apps: apps/install.sh picker, installer conventions, full app catalog |
| SYSTEMD.md | Systemd units (autostart.service, ssh-agent.service), feature-flag gating, bash completion |
| DEV.md | Developer guide: architecture, conventions, how to add tools/apps/features, commit guidelines |
| AGENT_Context_Project.md | Single-source context doc for AI agents working on the repo |
| algorithm.md | ASCII diagrams: install flow, pos dispatch, compose up, config cascade, logging, vbox lifecycle |
