Environment variable for FUSE

I’m writing an application that needs to access a file as local on the file system. I know I can just go ahead and use anything I want but I was wondering if there was any prior use or consensus on an environment variable to locate where ipfs fuse was mounted. I was thinking of something like IPFS_FUSE and IPNS_FUSE that way when someone asks for say

ipfs://QmYwAPJzv5CZsnA625s3Xf2nemtYgPpHdWEz79ojWnPbdG/quick-start

I could just translate that into

file:///$IPFS_FUSE/QmYwAPJzv5CZsnA625s3Xf2nemtYgPpHdWEz79ojWnPbdG/quick-start

Might even be cool if the API would do a 303 redirect if it was mounted but I’d have to think if there were any problems with that.
