I apologize; not having used that Handbook chapter's method for setting
up jails, I misunderstood parts of it. At least.

Okay, I've got it. I'm still unsure about the Handbook change; more on
that later.

In setting up a jail, you get a lot (nearly complete) freedom in setting
up the paths any way you want. For mounting many of the filesystem
read-only and sharing the underlying copies between multiple jails, you
necessarily end up with aliases for a number of paths.

I may still be wrong, but if so I'm about to be wrong in a new way.
It seems to me that the Handbook advice includes linking the
/s/usr-local onto /usr/local inside the jail. This is highly desirable
for regular users because having /usr/local/bin in a PATH works just
like on a real system. If you have that working, then I don't *think*
you should need to set PREFIX either.
My apologies again for shooting from the hip.
