Not true, This is NOT the UNIX way.  I suggest you check out the
man pages for "diff", "cmp", etc...

Diff:
       An exit status of 0 means no  differences  were  found,  1
       means some differences were found, and 2 means trouble.

cmp:
     The cmp utility exits with one of the following values:

     0     The files are identical.

     1     The files are different; this includes the case where one file is
           identical to the first part of the other.  In the latter case, if
           the -s option has not been specified, cmp writes to standard output
           that EOF was reached in the shorter file (before any differences
           were found).

     >1    An error occurred.

By analogy, integrit should return 0 on success, 1 on difference and 2
on an error.
