''' -u, --uid UID The new numerical value of the user's ID. This value must be unique, unless the -o option is used. The value must be non-negative. Values between 0 and 999 are typically reserved for system accounts. The user's mailbox, and any files which the user owns and which are located in the user's home directory will have the file user ID changed automatically. The ownership of files outside of the user's home directory must be fixed manually. ''' If the usermod command is not going to change the ownership of the files outside the user's home directory, I guess we don't have enough reason to do that. Besides, searching files in rootfs is a very time consuming process.
