The lack of adoption is because it’s not a complete operating system.
Using sel4 on a server requires complex software development to produce an operating environment in which you can actually do anything.
I’m not speaking ill of sel4; I’m a huge fan, and things like it’s take-grant capability model are extremely interesting and valuable contributions.
It’s just not a usable standalone operating system. It’s a tool kit for purpose-built appliances, or something that you could, with an enormous amount of effort, build a complete operating system on top of.
Yes. I really hope someone builds a nice, usable OS with SeL4 as a base. If SeL4 is like the linux kernel, we need a userland (GNU). And a distribution that's simple to install and make use of.
I'd love to work on this. It'd be a fun problem!
seL4 needs a ‘the rest of the kernel’ to be like linux
It needs device drivers for modern x86 hardware. And filesystems, and a TCP stack. All of that code can be done in "SeL4 userland", but yeah - I see your point.
Are there any projects like that going on? It feels like an obvious thing.
