Flash image writer

I was under the impression that 'Flash image writer 'in M5 was a package that used DD and would make SD cards boot able so you could use it to make a Pi SD in fact that it was much like the red hat package. Should it be, because my one doesn't work? M5 is still a Beta so should I report it as a bug. Cheese doesn't work but I think that's a driver issue I duel-boot with M4 and chesse works in that.
