+This value is used to determine CONFIG_SHELL and SHELL which may get exported into
+scripts shared via sstate onto other systems.
+
+Some systems have /bin/sh -> dash and others /bin/sh -> bash. Bash is preferred 
+but sometimes we can sometimes end up exporting /bin/sh yet use bashisms.
+
+This patch puts bash first in the search results which avoids the bash/dash confusion.
