lgtm with one suggestion

http://codereview.chromium.org/6840005/diff/1/utility/dev_debug_vboot
File utility/dev_debug_vboot (right):

http://codereview.chromium.org/6840005/diff/1/utility/dev_debug_vboot#newcode109
utility/dev_debug_vboot:109: cd ${TMPDIR}
one suggestion: I feel it be much cleaner if you modified LOGFILE to be the full
path instead of 'cd'-ing into TMPDIR, and using a relative path everywhere. This
is just for extra sanity.
