1. Get in the habit of running rm -rf /root/bin (that's harder to misypte than rm -rf ./bin !)
2. Maybe put it in a script if you need to occasionally delete /root/bin
If you need to recover a system now, is it possible to get another Fedora box running, update it, and copy the contents of /bin from the fresh machine over to your other one?
