ubuntu live-cd persistent and also read-only
I have already a ubuntu live-cd running with persistency on a USB stick but I would also want to be able to launch it, loading all the saved preferences in the casper-rw partition, but without any modifications on those settings.
The idea is to have on the start menu 2 options:
1- start ubuntu saving changes (on the persistent partition)
2- start ubuntu not saving changes (not persistent, but loading the previously changed settings)
This way, I could save preferences incrementaly, but only when I opted for the option 1.
