The problem here is that most were doing their exiting w/in a subshell; exit within a subshell kills the subshell, not the parent. Not all scripts were using set -e (which would pick up the failing subshell); as such just rewriting them to remove the potential via eliminateing the subshelling. Beyond that, removed a couple of custom (working, although non-standard) approaches, and removed a duplicate common.sh sourc'ing w/in mk_memento_images.sh TEST=force 'find_common_sh' to fail, note the scripts fails to exit BUG=none Change-Id: Ia1108a091a6399ad6aedd3cade4a107f4411686c Reviewed-on: http://gerrit.chromium.org/gerrit/3905 Reviewed-by: Brian Harring <ferringb@chromium.org> Tested-by: Brian Harring <ferringb@chromium.org>
