Quiet mode introduced output reduction to console to limit technical info provided to end users. Previous informational output (previous default) now outputs this now considered additional information through INFO() calls, which either outputs to console, or debug.log Only DO_WITH_DEBUG should call LOG directly, so that stderr+stdout output is prepended with LOG into debug.log This fixes previous implementation which called LOG in DO_WITH_DEBUG calls and modified expected output to files, which was observed by @3hhh in output of GRUB entries when selecting boot option.
