Ok, this is real simple, tar an entire Linux system with the --verify
and --totals tar option.

The problems that occur are:

 1) Files that have not changed are listed as changed in verify phase,
example messages below.
 2) The get a variety of messages that franky do not make much sense
as being valid issues, examples listed below.
 3) "Total bytes written: 160358400 (153MiB, 423KiB/s)" incorrectly
calculated when tar file is verified.  Current calculation of /s is
half of actual written speed.  i.e. the time used to calculate
included the verify time and supposed to be the "written" time taken. 
The /s is correct when one does not use the verify option.
 4) During the verify, the tar program will go into an infinite loop
and never complete the verify.

All of the above can be duplicated 100% of time.  I therefore expect
you should have no problems duplicating the above.  The 1.14 release
seem to add in the "File fragment" messages which never happened with
the SuSE tar-1.13.25-298 version.  The infinite loop and compare file
on verify problems have continued to be onging problems.

Example messages of verify part of tar:

Helpful changes:

 1) Informational message that verify has started.
 2) The "Total bytes written: " message written out at end of tar file
written and closed, so it is indicated before verify starts.
 3) A "Total bytes compared: " message for end of verify.
 4) A message that indicates if "Total bytes written: " and "Total
bytes compared: " are different.

Please BCC me by replacing after the "@" as follows:
TLD =         The last three letters of the word "internet"
Domain name = The first four letters of the word "software",
              followed by the first four letters of the word
              "homeless".
My appologies in advance for the jumbled eMail address
and request to BCC me, but SPAM has become a very serious
problem.  The eMail address in my header information is
not a valid eMail address for me.  I needed to use a valid
domain due to ISP SMTP screen rules.

Please note: You may experience delays in my replies.  I will
             reply.

             This is due to major restoration activity to my riser
             section of the building.

             My internet access will be limited to a couple weekday
             evenings.  Weekend access will be a bit better but
             limited as an indirect consequence of the restoration
             work.

             If for any reason you need a more immediate reply or
             fail to receive a reply, please phone and leave a
             message.  If you do leave a phone message, please note
             that I may not be able to hear the message and/or
             reply until the evening.  This will be due to the
             extensive noise levels of the restoration work
             activity drowning out most other volume levels of
             sound.

             The work starts 22 July 2002.  Based on similar
             experience to other sections of the building I would
             estimate the major noise element of the work to be
             about 4+ weeks for my riser.  There will be secondary
             instances once other ajacent riser sections are done
             that will have a similar impact, but for lessor
             periods of time.

             My appologies in advance, but this is mandated work
             that must be done.
