Changes from V4:
1. Take into consideration the possibility of whitespaces in
/etc/passwd and /etc/group
2. Change bbfatal in perform_usermod and perform_groupmod to bbwarn.
Please see detailed reason below.
PackageA pulls in userA.
Now we want userA to map to a fixed user ID without having to worry
whether PackageA is installed.
We can now use the following configuration to achieve this requirement.
EXTRA_USERS_PARAMS += "
usermod, -u 2013 userA; \
"
What happens files that userA might have already created outside the
home directory? I know that usermod will fixup the home directory and
some mail related files.
Sau!
OK... I misunderstood you comments ..
Here's what manual says about this situation.
'''
-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.

According to the manual, how the home directory is handled is
controlled by the options.
'''
If the -m option is given, the contents of the current home directory
will be moved to the new home directory, which is created if it does
not already exist.
-m, --move-home
Move the content of the user's home directory to the new location.
'''

After this configuration, if PacakgeA is installed in our image, the
user ID is modified to 2013;
otherwise, there's no change in /etc/passwd, i.e., userA will not be
added to /etc/passwd silently.
Hope this information will be useful.
