Limit racks to front-mounting only

[candlerb]

There are racks which only have one set of rack ears and/or no rear access: e.g. wall-mount racks, racks in street cabinets.

I would like to propose that there's a checkbox for these racks to say "Front mount only". It would prevent you from mounting stuff on the rear face, and would hide the rear face in elevations.

The workaround we're using is to create a dummy device type called e.g. "Unusable space 42U" which is 42U high, half depth, and then mount an instance of that device in the rear face. It seems like an ugly way to stop the rear face being used though.

Aside: I imagine this could be useful for 2-post racks too, although maybe you want to mount some things facing one way and some facing the other. In that case, you want to avoid the "front" and "rear" spaces occupied concurrently. You could set the device type to "full depth", but that may not be true of the device type in general, when it's used in normal racks. In this case, a rack setting "treat all units as full depth" might be worth having.

Hence it could be a three-way setting:

• Normal (Front and Rear can be occupied simultaneously by non-full-depth items)
• Two-post (Front and Rear cannot be occupied simultaneously)
• Front only
