Hello, when updating the German translations of the shadow package, I encountered strange things in the documentation. For example an option --non-unique for the commands useradd and usermod. With the first, the system administrator is able to force the system to create a new user with an ID that already exists, which is related to another user.
One effect I would expect after using useradd with this option is that files and directories are owned by two persons - as the UID of a file indicates the owner. Has anybody an idea about the purpose of such an option? >From my point of view it is necessary that the respective manual pages explain why one might use such an option and / or warn what a mess might be created with it. On the debian IRC channel, one comment on this problem was, Linux is a friendly operating system. It will not prevent users from shooting themselves in the foot.
