I have to acknowledge being an old timer U*ix system administrator. Software to be used by everybody had two possible locations:
/usr/bin /usr/local/bin
The best example is gcc and family.
Now I find myself in a new world. My node installation lives in:
/home/david/.nvm/versions/node/v14.7.0/bin/node
So I added the corresponding directory to my path.
How/where should the node package be installed? It would be done and owned by root, of course.
