Having had a few days to reflect, here are a few opinionated reactions. As usual, YMMV…
The Kry10 folks say that they want Elixir web developers to become IoT engineers. This may happen, but I think the infrastructure may need some love before it’s really going to be widely attractive to these folks. Basically, they will want most of the usual Linux amenities.
Although the IoT use case has a number of peculiarities, it’s basically a “self-contained, networkable processing node”. So, it’s a close relative of cell phones, desktop and laptop computers, smart watches, tablet computers, etc. Clearly, all of these use cases could benefit from a robust and secure OS, but that isn’t all they need.
Specifically, many instances of these (including some IoT devices) need an easy way to drop in vanilla Linux programs. Ideally, these would be Rust crates, such as the upcoming version of the Fish shell.
However, if C/C++ apps are all that are available, that should be a safe and reasonably easy option. One way of accomplishing this would be to run a Linux VM on top of Kry10. The postmarketOS folks use something like this approach:
postmarketOS is based on Alpine Linux, which is so tiny (less than 10 MB in size) that development of pmOS can be done quickly on any Linux distribution. We install Alpine in multiple chroots to cross compile packages, build and flash postmarketOS, run it in a VM with QEMU or interactively port new hardware.
To be clear, I don’t really expect all of this to happen immediately, but this could (for example) allow a supercharged version of postmarketOS to be developed. So, I’m really hoping that things head in that direction (on a pony :-} ).
