I'm interested in these kind of kernels to run very high performance network/IO specific services on bare metal, with minimal system complexity/overheads and hopefully better (potential) stability and security.

The big concern I have however is hardware support, specifically networking hardware.

I think a very interesting approach would be to boot the machine with a FreeBSD or Linux kernel, just for the purposes of hardware as well as network support, and use a sort of Rust OS/abstraction layer for the rest, bypassing or simply not using the originally booted kernel for all user land specific stuff.

i might be wrong but if it's ABI compatible the same drivers will work?

p.s.: i was wrong

>While we prioritize compatibility, it is important to note that Asterinas does not, nor will it in the future, support the loading of Linux kernel modules.

in general the ABI is kernel<->user space while the ABI (and potentially even API) on the inside (i.e. for drivers) can change with every kernel version (part of why it's so important to maintain drivers in-tree)
