Symlinks are not a bad idea (I don't need a GUI to create symlinks thanks ). It's just not the way I was hoping to organize things (I had organized my mounts this way on my current file server).
Thought it would be relatively straightforward because of the (seemingly) clean way it's all declared in config.xml but it sounds like it's more of a slippery slope than I realized based on my early (sadly partial) success.
At the risk of tempting you on to the slippery slope, aaron mentioned it would cause problems... besides the "ui miss" what else might go wrong? More out of curiosity on my own part at this point.
