I doubt that crontab is likely to return an exit status - there's nothing
in the man page to indicate it, and it is an interactive app (mostly).
You might get a return from the _shell_ if it failed to execute crontab
for wahtever reason.
Wiser heads than mine may be able to offer more info; or scratch around
in the crontab source. (I was going to say older heads, but that cuts the
options down considerably)
