Good question!
Although Sedum plants (and especially stonecrops) are very tough, Roundup is a potent herbicide and, of course, it doesn't discriminate between plants you want and plants you don't want.
If you are going to use Roundup, I highly recommend getting a sprayer with as little misting as possible. You want to be very precise when it comes to Roundup. Also, try not to put Roundup in the soil, as much as possible, because it can stay active for a little over a year, although the reports on this vary quite dramatically.
Roundup enters a plant by being absorbed through it's leaves, so you shouldn't have to put any on the soil directly.
I also should tell you that the active ingredient in Roundup, glyphosate, has been declared a possible carcinogen by the World Health Organization, although the EPA has said it's not.
If you end up not wanting to use Roundup, I would just try to pull the weeds by hand. Stonecrops tend to be very aggressive in beds and, if they get established, are very likely to choke out all their weedy competitors. As a matter of fact, you may end up needing to weed this plant out of where it's not suppose to be. I hope this helps!
