 /etc/init.d/
              The directory containing the actual init scripts.

        /etc/rc?.d/
              The directories containing the links used by init and managed by update-rc.d.

        /etc/init.d/skeleton

              Model for use by writers of init.d scripts.


 update-rc.d updates the System V style init  script  links  /etc/rcrunlevel.d/NNname
       whose  target  is  the script /etc/init.d/name.  These links are run by init when it
       changes runlevels; they are generally used to start and stop system services such as
       daemons.   runlevel  is one of the runlevels supported by init, namely, 0123456789S,
       and NN is the two-digit sequence number that determines where in the  sequence  init
       will run the scripts.

NFS mount add in fstab _netdev instead of default | firewall-cmd --list-all

By OK -
Redhat recommends us to add  _netdev  option for NFS file system in /etc/fstab. So that they can be mounted after starting the networking service. Alternative ways to refer to partitions: Label : LABEL=label Network ID Samba : //server/share NFS : server:/share SSHFS : sshfs#user@server:/share Device : /dev/sdxy (not recommended) Example #1 //192.168.1.134/share_name /mnt/share_name cifs username=server_user,password=server_password,_netdev 0 0 ^ Path to your share ^ Mountpoint ^ Username ^ Password ^ See note A Note A: The  _netdev  options makes sure the mount is only attempted AFTER a network connection has been established. Example #2 10.10.10.1:/vol1/fs1 /data nfs defaults,_netdev 0 0 ============================ [root@localhost ~]# firewall-cmd --list-all public   target: default   icmp-block-inversion: no   interfaces:   sources:   services: dhcpv6-client high-availability ssh   ports:   protocols:   masquera
