Currently, the scripts in src/scripts have multiple implementations for handling when common.sh fails to load, some of which are buggy. To simplify the boilerplate, these scripts now just exit if common.sh fails to load. The shell itself will print the following message if common.sh is not found: /usr/lib/crosutils/common.sh: No such file or directory BUG=chromium-os:32442 TEST=Run these scripts with and without common.sh installed.
