I updated my Centos 7, and it's awaiting a reboot.  The version of 
shim says 15-7, which I presume is the bad one.

What do I need to do?  Obviously, a reboot will encounter the 
failure.  Or, should I perform "yum update" periodically and wait for 
shim 15-8 to appear, and only after that do the reboot?  Or is there 
some other remedy?

And by the way, I'm amazed at the speed with which this problem was 
addressed and a fix provided.  You guys work wonders.
