While trying to add my autotest test to the wifi_perf test suite, I found I was unable to upload the change to gerrit.

Other test changes uploaded just fine.

But with this suite change, I get:

$ repo upload .
WARNING: Scripts have changed since pre-upload was allowed.

Repo must run the script:
  /usr/local/google/home/bfreed/chromiumos/src/repohooks/pre-upload.py

Do you want to allow this script to run (yes/yes-never-ask-again/NO)? yes

- To disable some source style checks, and for other hints, see <checkout_dir>/src/repohooks/README
- To upload only current project, run 'repo upload .'



I was told to run utils/build_externals.py in autotest/files outside the chroot, but that fails with:

I have to fall back to 'repo upload --no-verify .'.
