Concernant le code d'erreur, il me semble, d'après le "Shell and
Utilities volume (XCU)" de la "Version 3 of the Single UNIX Specification",
http://www.unix.org/version3/online.html

De plus, l'option -X de bashdb permet de tracer ligne à ligne
l'exécution, et on obtient un message d'erreur un peu plus parlant:

Ouais. De toute façon, ce genre de script doit s'exécuter en root, non?
Le message suivant, qui apparaît avec la manipulation à la fin semble se
rapprocher du problème.

Bon. À creuser. /usr/share/debconf/frontend est bien un fichier en
Perl... Encore de la documentation à lire en perspective...
Merci pour vos indications instructives.
