If I only create a single snapshot... it is active... and there is no other snapshot to switch to... *THAT* is why I need two snapshots... one I called the "base".  If you only have one snapshot... there is absolutely nothing you can do with it... other than delete it... which merges it down... and you are stuck with it.

I know that doesn't seem how it should work... but so far as I can figure out, that is indeed how it works.

I single snapshot is basically worthless.

I would love to be wrong about that and if someone can show me otherwise I'm definitely ready to receive the set of instructions.

TYL,
