Re: [uml-devel] [RFC] UML kernel & rootfs bundle with every kernel release ?

Why? I've never understood what a framebuffer gives you that you
don't have now.
Just like the network auto-configuration via dhcp, it would allow users to download images+kernel and run them like appliances without understanding anything about X or UML, just click and run.

mhh, i also think framebuffer would be nice, but the main idea behind my posting is have some recent linux kernel up and running without any effort - with main focus on kernel, not on apps.

sure, it would be nice to have X for the unexperienced users, but if you run uml and get networking up and running, you just do ssh -X into your uml and then you have your X. those people who run the latest kernel for testing special things are not unexperienced, but having a packaged kernel+rootfs "ready to run" would also make _their_ life easier. think of testing several kernels in parallel to find/fix regressions.

booting into something graphical with kdm/gdm login, firefox inside etc would be really nice, but that would be probably overkill for the purpose it should serve. framebuffer and X could be added later to uml, and i`m sure, it will exist one day.

btw - i think besides that packaged uml+rootfs, the same thing could be distributed in other formats, i.e. qemu, vmware, M$ virtual pc (add your favourite v12n solution here)

We are all capable of setting up Xvfb here, but most users are not, which is why they download ready-made images.
It would also make it a lot easier to focus on writing a management UI, hell if there isn't one shortly after, I'll do one myself!
Think of a UML browser image (running IE via wine in a limited image with just X + wine + IE - I would much prefer that to having wine+IE installed locally), testing framebuffer apps like gtk-fb/cairo-fb without risking your dev environment, etc...
