Unfortunately, this is what I feared. Suppose I find commit hash abcdef for 20250215 and hash ghijkl for 20250315, i.e, the 2 commits roughly a month apart. I can do % git checkout abcdef Now, I do the usual buildworld/installworld including the etcupdate steps. I need to rebuild drm-515-kmod port. Test to see if drm works again, % git checkout main (to recover the main branch). % git checkout ghijkl Repeat the world dance. -- Steve
