 mount bind problem

I have set on fstab /home with 'mount bind' but it seems like bind
is not effective.
Indeed. By default, nothing mounts "bind" filesystems. The init
scripts don't read the hole fstab file, there are filters to mount
only some filesystems types. If you want to mount the "bind" FS on
boot, you need to add the related commands into /etc/rc.d/rc.local.

Nonsense!  I'm also running CentOS 6.7 and have several bind-mounts
in my /etc/fstab:

   /var/home            /home           none  bind   0 0
   /var/lib/libvirt/etc /etc/libvirt    none  bind   0 0
   /srv/news            /var/spool/news none  bind   0 0

All of them occur automatically when the system boots.  The
"mount -a" in /etc/rc.d/rc.sysinit takes care of them just fine.
The filter on that command is _excluding_ certain types.  Note
that the first two letters are "no", which applies to all the
listed types:

mount -a -n -t nonfs,nfs4,smbfs,ncpfs,cifs,gfs,gfs2i,glusterfs -O no_netdev
