…k's pipe 40nodebb reads nodebb.py's standard output for APP_PASS=, and dialog draws on standard output, so an interactive first boot would freeze with the box drawn into the pipe (the bug keel-wordpress 19.0-3 hit on Proxmox on 2026-09-30, keel-mariadb#20). The answers go to a duplicate of that pipe and standard output becomes the terminal the hook checked on standard input, else /dev/tty; without either the script names secrets.app_password instead of a traceback. tests/dialog.bats runs the script as the hook does inside script(1) and fails on the old code.

firstboot.d/40nodebbreadsbin/nodebb.py's standard output forAPP_PASS=, and dialog draws on standard output, so an interactive first boot would freeze with the box drawn into the hook's pipe: the bug keel-wordpress 19.0-3 hit on Proxmox on 2026-09-30, fixed for dbpass.py in Keel-Linux/keel-mariadb#20.Fix: the same pattern. nodebb.py keeps a duplicate of the pipe for the KEY=value answers and points standard output, which dialog inherits, at the terminal the hook checked on standard input (else /dev/tty). Without any terminal it exits with a message naming secrets.app_password instead of a traceback. The hook is unchanged.
Tests:
tests/dialog.batsruns the script as the hook does, output redirected, inside a real pseudo terminal (script(1)), with a libinithooks stand-in whose get_password refuses unless fd 1 is a terminal; it fails on the old code and passes on the new.
