The rack eyelets are above the disc caliper. Which puts a rack really high above the wheel and way too far forward. Now I only go bike camping once a year, so buying a new bike to address this not really a good solution.
So I went looking for a solution to fit a rack on my bike. Tubus makes an adapter kit for mounting a rack on the rear skewer which looked like it would work.
The kit includes a longer rear skewer, an assortment of spacers and a set of nuts and bolts.
On the drive side it worked fine.
On the non drive side, aka the disc caliper side I used the Jandd Disc Brake adapter kit to move the rack arm out further from the dropout.
You can see why I need it clearly in this picture.
Now the Seven Mudhoney has a brake bridge with a single spot for attaching a fender or rack, but I wanted to use two rack struts to hold my tent and camping gear. So I used the Tubus Clampset. which really to be frank is a high end version of a p-clamp. But it is much more secure and it works perfectly. They come in a variety of sizes. So measure your seat stay before you order them.
I bought them online from Wayne @ the touring store, and he warned me that this setup would probably not work. But I lucked out and it worked fine. I have used these with a Jandd Expedition Rack and Jannd Mountain Panniers for commuting and bike touring.
