This is supposed to just work, and if it doesn't it's a bug.

It appears s-v-r.s should have an After=s-r.s but currently does
not. The fix should be easy: just add it to the unit file. Event
better, prep a PR and submit it upstream and we'll merge it.

Alternatively, file an issue, and we'll look into it, eventually (or
is there already one filed?).
