That's not true. Upgrades can fail. It's rare but it happens.
I wrote the FAQ entry and it also says:

| BEWARE: It's possible to kill a system by either upgrading the wrong
| firmware or the upgrade doesn't finish properly for any reason. Don't

It's easy to download the wrong firmware to a machine.
My favorite example is installing 715/100 PDC on a 715/100XC (need a
"dagger" card and working 715/100XC to resurrect the dead 715/100XC).
I've done it and know of others who've done it. Sounds stupid but
it happens.
