cifs mounting multiple times

[Tucker Cunningham <tucker@intapp.com>]

hi -
 I noticed that if you run multiple mount commands for the same cifs share
onto the same mountpoint, mount does not throw an error, it simply
stacks up entries in the mounttab.  This seems inconsistent with other
mount commands, which only allow something to be mounted on a mountpoint
once.  Is this a feature that I'm unaware of, or a bug? 

example:

tucker@buffalo:~/temp$ sudo mount -t cifs //sloth/fs cifs -o 
user=tucker,password=*****
tucker@buffalo:~/temp$ sudo mount -t cifs //sloth/fs cifs -o 
user=tucker,password=*****
tucker@buffalo:~/temp$ sudo mount -t cifs //sloth/fs cifs -o 
user=tucker,password=*****
tucker@buffalo:~/temp$ sudo mount -t cifs //sloth/fs cifs -o 
user=tucker,password=*****
tucker@buffalo:~/temp$ mount
/dev/hda1 on / type ext3 (rw,errors=remount-ro)
...
cheetah:/export/usr_local on /auto/usr_local type nfs (ro,addr=192.168.1.7)
//sloth/fs on /home/tucker/temp/cifs type cifs (rw,mand)
//sloth/fs on /home/tucker/temp/cifs type cifs (rw,mand)
//sloth/fs on /home/tucker/temp/cifs type cifs (rw,mand)
//sloth/fs on /home/tucker/temp/cifs type cifs (rw,mand)
tucker@buffalo:~/temp$

Thanks for your help.
