Maybe, but I'd like to see an inline explanation of what this confusing new setting means and a better patch header that provides some motivation for this change. To my eyes, the word "default" is over-used here. If I *don't* specify the new "default" flag, surely I'll get default behaviour, won't I, by definition? And if I do specify it, I'm asking for default behaviour too, so isn't it redundant? Alasdair -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
