LiberSystem - the new OS written in Rust

Дата публикации: 07-07-2026 23:19:23

I like Linux, but there are a few things about its model — and the Unix model in general — that I have disliked for a long time, especially:
the idea of “everything is a file”. Historically, it probably made sense, but today we often need different representations of all kinds of system resources, for example as serialized objects, etc.
it seems quite messy to me to put files on disk, devices, processes, sockets, system information, and so on into one single tree structure.
on top of that, allowing mount points anywhere in this structure, which after being unmounted can make the same path point to a different device, feels almost dangerous to me. For example, after a reboot, some storage might fail to mount and services may start writing to the system disk instead. Sure, this can be prevented somehow, but those are already workarounds.
... and a few other things.
So I asked myself: If I were designing an OS from scratch, how would I do it differently?
And so I designed and developed my own kernel and userspace, and the result is my experimental open-source system — LiberSystem
A microkernel OS written in Rust, based on typed objects, capability-based security, isolated services/drivers, and explicit volumes instead of classic mount points.
I do not see it as a replacement for Linux, more as an experiment.
I would be interested to hear what you think: does this direction make sense to you, or is the Unix model still the best approach in your opinion?
