Evidently part of my issue is confused over PREFIX vs LOCALBASE. The most
detailed thing I found was here:

    https://www.freebsd.org/doc/en/books/porters-handbook/porting-prefix.html

Neither is documented in make.conf(5) and I didn't find definitions online.

This is interesting - see below.

I want system-provided tools to live elsewhere so I can reserve /usr/local
for its traditional purpose.

Where should I have learned about this? I'm generally pretty good with
search engines, and I was struggling to find how to do this, found nothing
specific to Poudriere, and found the link I noted above that made me think
PREFIX was what I wanted.

I also read through this stuff, which didn't really clarify this:

    https://reviews.freebsd.org/D12666
    https://forums.freebsd.org/threads/prefix-and-localbase-path-aka-compat-any-ez-way.16773/

I tried setting both to /opt last night, and saw lots of breakage. I'd be
happy to try again with only LOCALBASE, but per Yasuhiro's note, there
seems to be a large number of references to /usr/local hardcoded in /etc.


Is there a knob that's honored for general builds such that these
references point to LOCALBASE? Or is LOCALBASE support largely vestigal and
painful to use nowadays? Between these two very good responses, I'm still
left unsure about what's supported and how to go about it comprehensively.
