cgroupsv1 removal (e.g JVM) ([Flatcar#1884](https://github.com/flatcar/Flatcar/issues/1884)) - Fixed the QEMU launcher script to include HVF acceleration on arm64-based Macs for faster performance ([Flatcar#1901](https://github.com/flatcar/Flatcar/issues/1901)) #### Changes: - Increased all partition sizes: `/boot` to 1 GB, the two `/usr` partitions to 2 GB, `/oem` to 1 GB so that we can use more space in a few years when we can assume that most nodes run the new partition layout - existing nodes can still update for the next years ([scripts#3027](https://github.com/flatcar/scripts/pull/3027)) - Reduced the kernel+initrd size on `/boot` by half. Flatcar now uses a minimal first stage initrd just to access the `/usr` partition and then switches to the full initrd that does the full system preparation as before. Since this means that the set of kernel modules available in the first initrd is reduced, please report any impact. - Scaleway: SSH keys are now fetched _via_ Afterburn
