...and to @comet424
I wasn't able to perform the 2.8.0 update this weekend, but when I got to the school this morning, it worked perfectly!
I appreciate the support from both of you, and from Netgate.
The backup/standby pfSense instance is back in place and ready in case I have a hardware failure, or a failure of the gray matter between my ears!
My best to all of you.
