Try the ones in the kb - hopefully, there isn’t some weird broken thing somewhere that’s going to cause problems… if it doesn’t, have a look in the Linux section of the forum. This, for example, seems like something you might run into.
Thing with ROCK is that by being an appliance, it’ll shield you from that kind of weirdness, and that’s a good thing, even if, yes, we ALL get the frustration of having a locked-down black box sitting around picking its nose when it could do more interesting stuff than feed music a few hours a day…
