Actually, `getmntent' already does the footwork for you: it returns
the string "ram" in the mnt_type member of the struct it returns, for
RAM disks.

Checking for the magic volume label is not a good idea, in my
experience: many RAM disks have all kinds of arbitrary strings there.
`getmntent' pulls out some trickery to find out whether a given drive
is a RAM disk.
