Ben, ça dépend sur quelle distribe tu es. Certaines font ça un peu goret,
d'autres plus sérieusement. Mais je ne vois pas vraiment de manière de les
retrouver.

J'ai joint les permissions sous Debian... J'ai zappé les lignes de même
groupe, ainsi que les liens symboliques (ils ont lrwxrwxrwx comme
permission). J'espère que ça t'aidera.
