Some failures aren't "random". There are a few common classes of
errors, common enough that there are even de facto standards for exit
codes to represent them, the most common probably being usage errors
(with a corresponding exit value of 2).
Of course then there are sub-system programs, such as mail delivery
agents which are supposed to return common codes with meanings defined
in the BSD-standard <sysexits.h> header file (which unfortunately has
gone against the aforementioned de facto standard even though I'd dare
argue it came second).
It would seem to me to be a very good thing to try and continue to
"standardise" on using the manifests defined in <sysexits.h>.
