Hardware bombs are nothing to do with the OS surviving a power cut.
Indeed, but lots of kit will run happily for years *until* it gets turned

I know.
I once installed a xenix OS running on a 286 for a project.
We used it for about 2.5 years and then finished the project.
We forgot to turn it off and it was found ~12 years later sitting in the
bottom of a rack the IT department when they wanted to move the rack.
it was still up and running without a reboot.
