Last change on this file since 2167cfe was 7df280d, checked in by Joe Ciccone <jciccone@…>, 17 years ago

Change /bin/sh to /bin/bash in the bootscripts because the bootscripts use bashisms. Having ash linked to sh will cause errors. Thanks to Bigdassaved for providing the diff and Copper for bring up the issue.
