Yes, they're getting here.  However, I should have clarified a point
(just like I noted that the original posting didn't clarify the point
:-).

This made the exact point that I failed to...

There are more than a few people who insist upon changing default
shells away from /bin/sh to other shells including ksh and others.

Prudent or wise?  Your decision.  (Although a real cron will warn you
that the commands will be executed with /bin/sh.  What does a stock
3b1 do if you change your default shell and run a cron job?)

However, if run as ksh, the failed cd will NOT cancel the execution of
the script.  So, even if safe under a cron job, it may not be safe
under a manually executed job.

And since so many people are panicking about it and beating it into
the ground (which was a point I _did_ make), then just "solve" it and
quit letting it eat your cerebral cortex.  Seeing everything from
comments about "reprehensible" to lawsuits, it's just not worth
discussing it anymore since people are just not thinking rationally
about it.  Just fix it, and "Don't worry, be happy."
