RESTART autofs ... systemctl restart autofs ... service autofs restart

Update size? Any issues?..call for help. New Kernel?
-----------------------------------------------------
yum check-update

OEL6 or 7

uname -r 

If OEL7 then systemctl is used (and often /etc/init.d RC scripts)
of OEL6 only /etc/init.d RC scripts

------------------------------------------------------
Paths that must automount.

If an RC script (systemd should manage ownership) will be used to stop|start...
Confirm that there is a su oracle in the script.

sudo su - oracle -c /etc/init.d/rc-scriptname
