I installed a daily build 12.10 on my Mac to test livecd. I already had a pen drive formatted to ext3 labeled casper-rw.
I had to invoke the "other options" with the F6 button so that I could append "persistent", but it didn't work. I clicked "try ubuntu," started browsing the web, and did a restart. When I ran the liveCD again, the persistence failed.
How can I restart in liveCD persistence? Thanks.
