This removes "printf -v <outputvar> <format> ..." which is only available in bash. These needless incompatible extensions to standard commands are a source of endless headaches. In this case, my previous "fix" to this file was incomplete, because I didn't not the braindead "printf -v" command. Also, this changes the shebang to call sh (which is already done by rcS, only the interactive execution now uses sh instead of bash). Signed-off-by: Alessandro Rubini <rubini@gnudd.com>
