In the future it would be better to send these types of questions to
the coreutils discussion list instead of to bug-coreutils, since it
isn't a bug and that way it won't open a bug in the defect tracker.
Since this isn't a bug I am going to close it.

In the GNU/Linux environment there really isn't a serial number
available.  What you are asking for isn't possible.

Yes.  You are correct.  But different vendors put different
information in there.  IBM AIX puts major release (4) and minor
release (3) for 4.3 for example.  There isn't a standard for it.

That is a vendor specific file with vendor specific information.
Every vendor puts different things in there.  It is intended to
indicate the operating system version.  But the format of the
information varies from vendor to vendor.
