I think you overestimate the money companies are willing to spend on memory and CPU for white line appliances. I actually have friends who have worked in R&D in the industry, cheap bastards wouldn’t splurge for an AmpOp if a BJT could do the job. If something required brains, a cheap small SoC was the way to go, with all its 64-256KB of memory.
A lot of those are running either minix, BSD, or some other ultralightweight OS. and those are definitely not Linux. Not even close.
Minix has not been updated in 10 years. It should not be used on anything connected to the internet.
Most “ultralight stripped down OS” will be built from linux these days. Usually Tiny Core Linux or Alpine.
What’s this Minux you keep talking about?
