Comment 9 for bug 1851123

The point of the work I did on this was to automatically save the installer logs to the media. I don't want to change the default behaviour. However, we should make sure other use cases are possible. You can put "nopersistent" on the command line to disable both creation and mounting of casper-rw. We should also make toram (and I guess todisk?) disable that too I guess.

Basically if you're doing anything unusual, I'm fine with not mounting casper-rw. But I want the default to stay the same.
