I get this question a lot because I use so much roasted garlic in my recipes, and the answer is: it depends. The smell of garlic roasting is a pleasant and mild aroma to me, so I don't think of it as a stink. However, if you are very sensitive to smells, it may bother you. It isn't the same as sautéing garlic, though. The aroma is much milder and almost sweet smelling. The most important thing when cooking with or roasting garlic is to not allow it to burn. Burnt garlic is not a pleasant smell or taste.
