hermitux VS cage

unikernels maybe. e.g. there is HermiTux

The definition of what a unikernel is needs to be narrowed down, a lot of these projects in the space (not all the ones listed above) have material differences that are not clear:

- some run only one language

- some require recompilation

- some essentially swap out libraries, others do something closer to dropping your already mostly static binary in a minimal disk image

- some build pid1 processes, others VMs images

Anyway, here are some additional entries in the space:

- https://ssrg-vt.github.io/hermitux/

- https://github.com/linuxkit/linuxkit (more embedded/minimal VM than unikernel)

- https://nabla-containers.github.io/ (runs on Solo5)

I am going through using Linuxkit to build AMIs for cloud providers now. I wouldn’t necessarily class linuxkit as a universal project because it doesn’t have the hallmark blurring of user and kernel space or kernel-as-a-library but you can customize the kernel so it’s an adjacent idea, and I think it’s the one most likely to be in actual use at non-hyperscalers.

What do you think of this, then? https://github.com/ssrg-vt/hermitux/wiki/Fast-system-calls-i...

I just had this in mind because skimmed it a few hours ago in the context of https://news.ycombinator.com/item?id=26142285

You... might be able to, kind of, depending on your goal... So the thing is, if all you need is a single screen (or at least, I've not run this multi-monitor) and you're just working around drivers that don't support Xorg, you can just run cage ( https://github.com/cage-kiosk/cage ), run xwayland on that, and run your real GUI on that. Of course, then you're skipping all the advantages of wayland except hardware/driver compatibility.

For "real" wayland, sibling comments are correct that you'd need a wayland compositor that reimplemented awesome.

> As a developer, I needed to port a custom Linux system to hardware that only has Wayland drivers and it was a giant pain. Wayland offers no advantage at all for that system but it broke a lot of functionality that relied on X in terms of window placement, etc.

FWIW, I've had decent luck running cage ( https://www.hjdskes.nl/projects/cage/ ), then on that xwayland, and then just ignoring wayland and running X clients. The result does still have some slight quirks, but it mostly works fine.

That did help me find https://github.com/cage-kiosk/cage/wiki initially I'm here there's other going down that path. Thanks

I thought this was going to be some development news with Wayland compositing going further: https://emacsconf.org/2022/talks/wayland/. Maybe it's because 29.1 was on my mind with the full Wayland client support being released.

If you want to just run one application in a modern way (yes, I'm assuming you agree that Wayland is desirable), then check out https://www.hjdskes.nl/projects/cage/.

You can run Wayland inside Xorg via cage[1] so you don't need to use a Wayland compositor.

Just ran into cage, seems useful.

It's kiosk mode. Sometimes related to POS. You can use https://github.com/cage-kiosk/cage (Wayland) for example.

Maybe starting with reimplementing something like this: https://github.com/cage-kiosk/cage would be the easiest?
