Hello Mahmood

What kind of OS are you using??

If you want to use automount, you have to setup automount.
  ex) http://freespace.sourceforge.net/guidod/howto/autofs.html

I you wan to mount /opt at boot time, but now you can't
 Could you please check autofs (If you are using RHEL, CentOS, Fedora...)

 # /sbin/chkconfig --list netfs
 netfs          	0:off	1:off	2:off	3:on	4:on	5:on	6:off
