When uploading a CL for src/platform/crostestutils/recover_duts/recover_duts.py, I was told that I should replace "import logging" with "from chromite.lib import cros_logging as logging".  But I was warned by a reviewer that this may not work on a DUT (this script runs on DUTs) and in fact a test image does not appear to contain chromite.lib.

If this advice is generally useful by all means keep it, but you may want to qualify it with "if the python environment supports it, use...".  I understand one will still have to skip the hooks to upload.
