a few points:
the kernel should be not upgraded by default (this is fixed)
these version files should not be modified, as explained in another thread... the system can be correctly updated but since it may not include -all- the changes, is better to keep a reference in the OS of what's the exact version of elive that was installed
this means, it may not include new packages selected on the OS, possible kernel updates, personal configurations, installer improvements, system configurations, etc...
more of these details / diferences are wrote in How to update your Elive, the correct way
