Thanks Stuart,
Before you answered, I put my stuff in /usr/local/(lib, bin). There was nothing in this location and it was already on the path. Would it be a mistake to leave my stuff there? Right now, /var is set to be in RAM.
Sorry, not really an LTIB question per se, but I appreciate your advice.
I suppose I need to read an RPM book to see what I'm missing as far as package management.

Hi Todd,
Your workflow is okay, except you're missing some kind of package
management if you want to easily be able to replace your own stuff.
Apple is not a Linux platform, so it's not fair to try to equate how
they manage content. Even Android does thing a completely separate way.
For Linux (LSB) put your stuff in /opt/_vendor_/{lib,bin}. However this
will only get you so far unless you use some kind of package management
system.
Regards, Stuart
