But the installed system fails after the package install is complete...

I got a message that said
"An error occurred while switching to the installed system." Along with something like 'no recovery possible, would you like to run the automated debugger?' The debugger is kind of interesting, it verifies a bunch of system packages. No problems are shown, as all the rpm checks pass. Then the install continues, but initrd creation fails. Then the install dies.

I think I'm going to go do a clean install now.
