Do you have a source for this? I can't find any. There was a bug that made NVRAM read only on some systems in 2017 (that was in ubuntu 17.10), but nothing else I can find. I can find some comments about trying to reduce the writes to NVRAM to avoid wear, but nothing specific I can find that actually says people have had NVRAM actually wear out. It would have been some years ago.
Years ago I worked on an avionics project where we were storing data in an NVRAM. We had to write code to manage the wear-out in the cells and if I remember correctly the wear-out was in the hundreds of thousands to millions of writes before problems would occur. I could not see normal usage causing wear-out unless someone were to have some kind of bug causing a high write rate. -- Alvin Starr || land: (647)478-6285 Netvel Inc. || Cell: (416)806-0133 alvin@netvel.net ||
