1. Redirect stderr to a different file. And check for that file being
more than 0 bytes before claiming the install completed succesfully.
2. Expect the unexpected. I am currently having issues with a "serious"
IT company over an install script that does not error checking and where
there are multiple error-prone steps between zeroing out the old config
and recreating a new one, which can leave the machine pretty much
brain-dead if Something-Bad(tm) happens in the middle of the upgrade.
