Ubuntu Engineering in 2025: A Retrospective - Jon Seager

This item was probably where the least concrete progress was made, though I probably could have predicted that. Many of the processes in the Ubuntu project serve to ensure that we ship resilient software, and don’t break users - so changing them in a hurry is not generally a good idea. … ... `sudo` implementation on Ubuntu 25.10, and uutils’ `coreutils` has *mostly* replaced the GNU implementation, with a few exceptions, many of which will be resolved by releases in the coming weeks. ... `initramfs-tools` until remaining hooks are ported. For each of these changes ( `coreutils`, `sudo-rs` and `dracut`) the previous implementations will remain supported for now, with well-documented instructions on the reversion of each change for those who run into unavoidable issues - though we expect this to be a very small number of cases. ## What’s Next?
