Are you including back in the day when we had to use windows device drivers via ndiswrappers?
I’ve managed to remove a critical library once but did manage to extract it from an RPM on another machine and manually install it. That was good enough to get me to the point where I could yum reinstall.
Pre-linux we had an HP workstation where the disc drive died and of course we had no backups. I managed to frankenstein the disc by connecting the platters on the broken disc to the circuit board of a working disc. This worked and I was able to back up the disk and reload on to a new drive.
And then we bought an 8mm tape drive for backups and I had to port some drivers to HP-UX to get it to work. But we had awesome backups after that!
