From: Chen Qi <qi.c...@windriver.com>
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.
