There's a better way.

Step 1 is the abandonment of getmntinfo—static storage considered  
harmful. If we go that way at all, then we should use getfsstat  
instead, which has us provide the storage.

Step 2 is the replacement of getfsstat, which gives us info on *all*  
devices, with statfs, which gives us info on one mount point (or any  
file thereon). It's the POSIX equivalent of -[NSFileManager  
fileSystemAttributesAtPath:], except that it gives a lot more info.

There's also a way to do it that involves - 
fileSystemAttributesAtPath:. Among the crumbs of information  
(relative to statfs) that it provides is the device number (dev_t).  
You can pass this to devname_r to get the filename of the device. The  
difference is that statfs gives “/dev/foo” whereas devname_r gives  
just “foo”. This is more roundabout than simply calling statfs, though.

I do thank Gus, though, for providing that section of FMKit, which  
started me on the above research. :)
