Luke, Thank you so much for in-depth instructions for setting up multi-node dev cluster on the same server. I have confirmed that the precommit hook now works, with your instructions, as non-root user.
Especially, the instructions on doing dev build for 3 nodes were very helpful! I will run a diff with my original installation to see what might be the issue, and report back if I find anything. Thanks again.
