# PDF OCR Hotfolder — Installer / Instanz-Manager für Debian 12/13
|
|
#
|
|
# Basis-Installation erfolgt einmalig (Code, venv, systemd-Template-Unit).
|
|
# Danach werden Hotfolder-Instanzen verwaltet:
|
|
# - Beim Erstlauf: mindestens eine Instanz wird angelegt
|
|
# - Beim Folgelauf: bestehende Instanzen werden erkannt; neue können ergänzt werden
|
|
#
|
|
# Unterstützt lokale System-User und AD-User mit lokaler UID (SSSD/Winbind).
|
|
