So you forgot to compile in support for sysreq. So what?  Do you care?

One of your start-up scripts is trying to read or write to the sysrq flag
in the kernel image, but your new kernel doesn't have that option
available.

In the "Kernel hacking" section of your kernel configuration, select
"Kernel debugging...Magic SysRq key," save and recompile.

Or search your startup scripts for the line that's trying to set that flag
and comment it out.

1. difference between /etc/rc.sysinit and /etc/rc.d/rc.sysinit ?

What is the difference between /etc/rc.sysinit and /etc/rc.d/rc.sysinit?
I am using Redhat 8. I did a diff on them and they are identical.
/etc/rc.sysinit is apparently a copy of /etc/rc.d/rc.sysinit since it
says that it is that file, even though it's not (see below).


#!/bin/bash
#
# /etc/rc.d/rc.sysinit - run once at boot time

I want to change something in whichever of these scripts is run at
bootup, but I don't know which one gets run.

Thanks,
Russell
