Good.

Because I could not tell about stages that were not explicit,
I had some notes about context that likely would be overkill
for notes to yourself.

Do some "df -m" commands while poudriere bulk has some
builder(s) running. You will see where things are
temporarily during the running build(s) each time.

/usr/local/poudriere/data/packages/main-default/ ends up
as the long term storage area for packages for your
"main" jail builds of packages --at least by default.

/usr/local/poudriere/data/logs/bulk/main-default/ ends
up as the long term storage area for the logs for your
"main" jail builds of packages --at least by default.

If you have thigns configured to save build failures,
/usr/local/poudriere/data/packages/main-default/ ends
up as the long term storage area for the saved failures
--at least by default.

(I'm not showing the detailed substruture below those
levels.)

http://www.zefox.net/~fbsd/poudriere_on_rpi4 looks unchanged
just now, not just for this but for any changes. May be some
other copy was changed or the old content is cached someplace?

But that buildworld buildkernel activity and rebooting to
the new installed system and updating
/usr/local/poudriere/poudriere-system should be done before
even the "poudriere jail -c". The quoted material may be
just out of order?

Late night operator error: "indented oddly" would
be what I was intending.

In what I saw, "FreeBSD:" left hand side was aligned
with the "enabled:" left hand side, both being indented
--or at least that is what showed up in the browser when
I looked at http://www.zefox.net/~fbsd/poudriere_on_rpi4 .

Whitespace may not have been well preserved in what I
sent out so the indentation detail might not have looked
the same in my note.

No joke. Just an error on my part.
