autofs mount point on same box?

[Frank Murphy]

Can a autofs mountpoint be used on the same pc?
man autofs if from 1997, still talks about ~/init*

Box has:
/md0 (boot,/)
/md1 (home)
/md2 (/shareyumcache)
/dev/sdg (swap) [can't see a benefit in raiding swap]

I want to use autofs to mount /md2 
into "/var/cache" so the result is:
/var/cache/yum/...

autofs.shareyum
yum  (mount options)  127.0.0.1://shareyumcache 
would that be correct?

why would anybody do this?
a bind-mount on your /etc/fstab is your friend

/shareyumcache  /var/cache/yum  none  bind

From my config:
/etc/auto.master
/misc	/etc/auto.misc --timeout=60 --ghost

/etc/auto.misc
WDC160		-fstype=auto,noatime,nodiratime			:/dev/disk/by-label/WDC160
WD500-Canyon		-fstype=auto,noatime,nodiratime			:/dev/disk/by-label/WD500-Canyon
WD500-MyBook		-fstype=auto,noatime,nodiratime			:/dev/disk/by-label/WD500-MyBook

Another way (from man mount):
...
      The bind mounts.
    	    Since Linux 2.4.0 it is possible to remount part of the file hierarchy some-
    	    where else. The call is
    			 mount --bind olddir newdir
    	    or shortoption
    			 mount -B olddir newdir
    	    or fstab entry is:
    			 /olddir /newdir none bind
...

Curious what the --ghost
couldn't see anything clearly in man auto.master

It will make mount points visible all the time.
Useful for gui access.
