Under Unix, does the "host:/path" syntax apply to every network
filesystem type (Andrew, Coda, etc.), or just to NFS?

Certainly ":" is reserved in Windows for use only with drive letters.
Is fs_name (above) always what appears in the left column for df?

But what about mapped drives, then?  They often appear as U:/whatever.
E.g. below, only c: and d: are local drives.  Not to mention drive
letter mappings set up with the "subst" command.

$ df

I would have thought it should really be looking at the filesystem type,
not the syntax of the mount point.  And I hereby confess that I don't
actually know the system call used to determine the filesystem type.

Aren't TODO lists wonderful?  :-)
