features/usb-automount.sh (installed via ./install.sh --feature, flag
usb-automount) mounts every unmounted removable block device at
/media/<label> — world-writable via -o umask=000 (fallback plain mount),
label-collision bump -2/-3, no-label -> usb-<name>. First root run
self-installs the hotplug udev rule (/etc/udev/rules.d/99-usb-automount.rules,
SYSTEMD_WANTS=usb-automount.service) + udevadm reload/trigger; an existing
rule is never overwritten. systemd/usb-automount.service (Type=oneshot,
WantedBy=multi-user.target) covers boot + hotplug + manual start, gated in
postinstall.sh's systemd loop exactly like autostart. Purpose: a plugged-in
stick is ready for pos system backup's post-verify USB copy without manual
mounting. Docs: SYSTEMD/SCRIPTS/README/AGENT_Context (tree, filetable —
postinstall.sh count corrected 152->163, it was already stale). Verified:
stub suite /tmp/opencode/usb-automount-test 47/47 green; make gen && make check.
- Move autostart.sh from bin/ to features/ so re-installs never reset it
- Add lib/flags.sh (flag_set/clear/is_set/value/list/status) + flag-reader/set/clear CLIs
- install.sh --feature copies features/* to /usr/local/bin with overwrite prompt, sets flags
- postinstall.sh enables autostart.service only when the autostart flag is set
- Document features & flags in README, DEV.md, AGENT_Context_Project.md
