I'm having a similar problem. Could somebody post some basic
instructions on how to properly use snapshots? I have spent the last
few hours experimenting and reading docs, but I haven't had any success.
I can produce a live-sn.cpio.gz file, but it doesn't result in
persistence. I have also tried creating a partition with the label
"live-sn", but still no success.
