This is where most people (previously including myself) would suck it up, start from scratch with a USB installer, try to remember all of the customization steps they took to bring the system back to its current working state, and restore user data. But I'm not the man I once was. I've been playing this game long enough. I don't go crawling back to the dusty install media when something as trivial as critical system files go missing or corrupt. I know what I did wrong and I can think of several creative ways to fix it.

I was already in the middle of building my system from source to track FreeBSD 13.0-STABLE, instead of RELEASE. So instead of using a rescue CD to copy just the right files back or completely reinstalling my system, I'll just <code>make buildworld</code> and upgrade/replace my system in-place to track STABLE. The install/upgrade/switching process is well-documented, and there are already difftools/mergetools responsible for making sure that all of the new artifacts go exactly where they're supposed to (overtop of your old or broken existing ones). @@ -118,4 +123,7 @@ After reviewing the list and ensuring you don't need those files, you can clean </code> </pre> +// TODO: pkg reinstall +//I'm a <code>pkg leaf | xargs pkg install -f</code> away from completely restoring those. + Redemption. I went from attempting to customize my kernel to annihilating <code>/usr</code> to restoring my entire system by building from FreeBSD's source tree via <code>git</code> and <code>make</code>. And I got an upgrade in the process too! Moving forward, I'm running slightly frequent automatic full-system snapshots. It should make it a lot easier to rescue accidental deletions of system files. I'm also going to take the time to learn more about the rescue disk process using the FreeBSD installer image. All told, not too bad for something that could have gone a lot worse. |
