Why will my NAS not mount at boot

My NAS will mount fine when I type mount -a but never on boot this is my fstab line:

// /home/osmc/Nas cifs rw,guest,vers=1.0,iocharset=utf8,_netdev,noperm 0 0

Can someone tell me what I am doing wrong and yes I dont want to use mnt or media to mount it.




// /home/osmc/Nas cifs rw,guest,vers=1.0,iocharset=utf8,_netdev,noperm,x-systemd.automount,noauto 0 0

Thanks Tom.
