I'd like also like to mention that my main concern with the ver_linux files that I found in my project was that the shebang line was " #!/bin/sh" instead of "#!/bin/awk -f" which is the shebang line in the ver_linux file in the patch. The patch wants to change the shebang line from "#!/bin/awk -f" to "#!/usr/bin/awk -f" so I'm not sure how that change would translate when I'm working with the shebang line "#!/bin/sh". Or perhaps Yocto has changed since that patch was posted and maybe the place /bin/awk is specified is different?
