I can think of two ways.  First, run lsmod (or cat /proc/modules) and
see if "autofs" shows up in the list.  If the use count is >0, then
you are probably trying to use autofs.

BTW, if you do have autofs installed, and this is a Red Hat box, just
"rpm -e am-utils".  You don't need (or want) the userspace automounter
if you have autofs.

The mount program uses it.  From mount(8):

       The programs mount and umount maintain a list of currently
       mounted file systems in the file /etc/mtab.  If  no  argu-
       ments  are given to mount, this list is printed.  When the
       proc filesystem is  mounted  (say  at  /proc),  the  files
       /etc/mtab and /proc/mounts have very similar contents. The
       former has somewhat more information, such  as  the  mount
       options  used,  but is not necessarily up-to-date (cf. the
       -n option below). It is possible to replace /etc/mtab by a
       symbolic  link  to  /proc/mounts,  but some information is
       lost that way, and in particular  working  with  the  loop
       device will be less convenient. Also, pathnames containing
       spaces are handled correctly by /etc/mtab but not (yet) by
       /proc/mounts.

I don't think I can explain it much better than that...
