just ran into an issue with debconf's debug logging, which I'm preparing
a patch for.
The issue is simple: When confmodule sends an unknown command to
debconf, it replies with:
"Unsupported command \"$command\" (full line was \"$_\") received from confmodule.";
However, this is only sent to confmodule (and possibly ignored there).
You would expect anything sent to confmodule to be printed when setting
DEBCONF_DEBUG=developer, but that doesn't happen for this error.
To reproduce, create this 'unknown-command' script:
echo foo >&3
Then run debconf:
matthijs@grubby:~$ DEBCONF_DEBUG=developer debconf ./unknown-command
debconf: DbDriver "passwords" warning: could not open /var/cache/debconf/passwords.dat: Permission denied
debconf (developer): starting ./unknown-command
debconf (developer): <-- foo
Notice that no reply is shown for the "foo" command. When injecting a
tee into the stdin of ./unknown-command, you'll see that there is
really an error reply.
I'm working on the simple patch now, I'll git-sendmail it over when I finish it
in a minute.
