I have Bazzite running on a BC-250 machine. A few weeks ago, I made some changes using rpm-ostree related to zram and swap. I had assumed that, because I used rpm-ostree, the changes would become part of the “tree” and I could rollback to the original settings. But when I went to look at Bazzite’s rollback tools, it seemed solely focused on rolling back to previous official releases, and I couldn’t find any reference to the specific changes I made.
