I have a remote home server updated to CentOS-7.2.1511 (as stated in /etc/redhat-release) but I have not re-booted since the update. The machine is currently running kernel 3.10.0-229.11.1.el7.x86_64.
I'm wondering if anyone has advice on any safety steps I can take before re-booting, so that in the event of failure I can give simple instructions to my daughter at the other end on how to get the system running?
Rather than initially involving a "remote hands" person... ... use "grub boot once" or in the case of grub2 it's called "grub reboot". ( Then only if it has a really bad fit should you have to involve a physical person. )
The operations are a bit different with grub2 than they were for grub1/grub-legacy.
