Just because some of the hardware and its control software may be stuck in ancient times doesn't mean that they wouldn't want to upgrade other software or add other hardware that requires a newer kernel to function.
- fisf 3y agoBut in practice, it is often not possible or allowed to simply add other software or hardware to those systems. Those are delivered and certified as-is and upgrades are a no-go.
- phkahler 3y agoYeah they could upgrade the processor. And since it apparently runs Linux already, most the software should be relatively portable. Now if they're using a 9-bit serial UART there may be a problem...
- not_the_fda 3y agoThey wouldn't, its too much of a risk. The update could break the control software and bring everything down. If its working don't touch it, otherwise you might bring down production and lose lots of money. A new kernel brings no value to a currently working system.
