AptiviUbuntu 25.10 will use Dracut
While Ubuntu 25.04 is still ongoing development, there has been progress in switching from initramfs-tools to Dracut. Those tools both handle initrd generation for booting into the Linux kernel in preparation for the full system boot. The Ubuntu engineers are working hard to migrate such tool to Dracut to ensure better bootstrapping by reducing hard-coded logic as much as possible.
Initially, Ubuntu 25.04 would have used Dracut as the initrd generator, but the work wasn’t complete yet, so the Ubuntu engineers have delayed the migration to after Ubuntu 25.04 gets released so that the next version of Ubuntu uses Dracut completely.
However, you have an opportunity to try out Dracut in Ubuntu 25.04 when it gets released. This is so that you can provide feedback to the Ubuntu team about your experience with the Dracut integration.
Ubuntu 25.04 will be the last version that uses initramfs-tools as the default initrd generator, with the October release of Ubuntu being the first version that uses Dracut. This is going to be exciting news for the next year’s Ubuntu LTS release that will be out in the next April.
