You're screwed when the firmware decides to write to the ESP though.
- Spivak 6y agoThis is 100% true but I haven't been so unlucky as to encounter firmware that does this under normal operation. This has been the "firmware doesn't understand software raid" solution for ages.
- yrro 6y agoIndeed, it hasn't happened to me but I remember reading about someone who discovered the hard way that their firmware fell back to storing boot variables in a file on the ESP for some reason. It's the sort of thing you only notice once you're staring at an error message, wondering why your ESP is corrupted. It's hardware RAID or nothing, at least for the ESP for me!
