We may want to add a user or group which does not logically belong to
any specific package. For example, we may want to add a user with the
name 'tester' to our image. Besides, we may want to delete or modify
user/group in our image.

This patch adds a variable, USER_GROUP_SETTINGS, which is dedicated
to these tasks. The configuration format is detailed in the local.conf.
sample.extended file.

This patch also adds a function, set_user_group, which happens at
the end of the ROOTFS_POSTPROCESS_COMMAND. It handles the settings
in the USER_GROUP_SETTINGS variable.

Why not use extra package just with user?

See "[PATCH v3 0/5] Allow xuser to shutdown (cover letter only)"

The issue is that the users don't want extra (empty) packages to just add standard users/groups. What they want is a post image-generation "configuration" mechanism.

Adding users/groups is one of the basic items that they want/need. This really has to be considered to be an administrative activity vs a distribution activity. (I.e. difference between creating a package and performing some kind of post-image action.)

The other issue with a package based approach is it then mandates changes occur by having to rebuild/reinstall packages. This is onerous in my experience, for something basic like this. It's really outside of the package manager's control.
