you absolutely need the debian chroot.  if you are not using the
coriolis2_chroot build process, instead for example using
$insert_OS_here, then for example, /usr/bin/python will be symlinked
to /usr/bin/python3, not /usr/bin/python2.  this *will* cause the
pinmux program to fail because it is python2.7 only.

no - git submodule update just has to be run anywhere inside the git
repo (just like any other git command).

i'm guessing "blind".  there's absolutely no good reason that i can think of.

without seeing a listing, or actually logging in to the machine and
investigating for myself, seeing the directory structure, and so on, i
have absolutely no idea.

the only thing i can think of is to run the exact same "make pinmux"
in other directories, and get / check it working there.

it cannot possibly fail in absolutely every one of the three separate
locations it's used.
