I realize that this is a useful feature and not a bug.
But as stated earlier, this is new territory, and I think some of us, who use live and persistent live drives may have problems to use drives with this new feature. So it would still be valuable to get a modification such that 'toram' alone will turn off saving log files to the casper-rw partition and make it possible to unmount it.
I installed Xubuntu when running a persistent live Ubuntu system
1. With the options 'toram' 'nopersistent'
It was truly live-only (and the installation worked).
2. With the default settings (no extra boot option compared what comes with the iso file)
The casper-rw partition received and stored an install log (and the installation worked).
