- Windows XP - Power went out at a critical stage of updates. Completely hosed the system, and wasted hours of my life having to rebuild (including rebooting multiple times to get updates installed again after the recovery).
- Windows 7 - Cable giving my router IP addresses. Called ISP tech support... they had me manually plug the cable in and type cryptic commands at a DOS prompt. Is that unacceptible too?
Also, I'm really baffled as to how the network going down could kill a Fedora update. The downloads happen before any significant filesystem modification in every version that I have ever used (certainly any recent one). I guess maybe some third party package does something weird during a POSTINSTALL script? I dunno.
