Many packages leave the user on the system because the local admin
might have assigned files to the user and those files might get
accessible to another user if the UID gets reused.
If you want to make sure, you can check whether deluser and/or userdel
are available and invoke the first binary you may find. If none is
available, leave the user as-is.
