Hello Steve,

Mouting the root filesystem Read/Write is required in order to save the vmcore information on the root filesystem, which is the sole intent of this script.

This is not introduced by the patch, but is present in the original script (Line 41). And panic is not called anywhere in there either. Once the vmcore gets copied to $rootmnt/var/crash, the root FS is remounted Read Only just before the end of the script which terminates by invoking reboot :

 mount $rootmnt -o remount,ro
 reboot

I hope I'm being clear enough.
