Frustrating.
I found this older post:
They suggest you can install timeshift on the live CD stick with yay.
"Yes simply install timeshift on the live USB and choose the restore snapshot.
yay timeshift
yay cronie
run timeshift . "
Problem is, I can’t use yay to install anything on the live CD.
It sees the network, Firefox sees the web.
Seems like this could work if I could install things on this liveCD.
