  • It still is! If you try and boot a kernel with nothing in /dev, you won’t get most of the kernel boot messages since /dev/console doesn’t exist. You need a basic set of device nodes in /dev before udev is started.

    If you’re going to rsync a system to new hardware and exclude /dev /proc /sys, it’s better to setup a new mount of your / to a different directory and sync off that, so you get the underlying stuff without the cruft.









  • I’d also suggest throwing more cores at it than you think it needs, and increasing the nic buffer sizes. This is what finally solved the random 1-2 minute outages I was seeing on lemmy.ca, turns out we were somehow saturating the queues even at relatively low traffic levels. (these issues might be specific to our model nic)

    Finally, make sure hardware offloading is disabled, and your CPU type is set to host.
