That may be, but I don't see how the change could make the situation worse. If the boot device detection fails, it will cause problems already at the vfs_mountroot() stage, and we won't even get to the point in the boot sequence where /etc/fstab is used. The kernels on the -sd0root and -wd0root images are identical and configured with "root on ? type ?", only /etc/fstab differs. -- Andreas Gustafsson, g...@gson.org
