Ubuntu 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.

@xeniac I know that this is the case, but it's not a technical unavoidance despite the #RaspberryPi being a non-#UEFI - #arm device.

  • Even on the old, #32bit boards.

The solution in that regard would be to boot into a #live / #setup mode like with #RaspberryPiOS for #i586-based #PCs and extend it to a setup that allows creating a new custom image with #LUKS - #FDE enabled and properly encrypted.

  • OFC on a #Pi0W that would mean one would've to plug in a 2nd MicroSD with a USB-Adapter but that's not the Point.

I'm not even demanding much, just a simple #TUI / #CLI setup like @ubuntu / #UbuntuServer has with basic customizations.

  • I'm not even expecting it to go so far as to offer including #dropbear - #SSH in the #initramfs so one can boot into the encrypted install and unlock it remotely. Just gimme the blinking cursor at the boot asking me to enter the password for the encrypted partition...

@trysdyn Granted, this is why I want to avoid as many packages as possible for OS/1337...

Because the likelyhood if such a #SupplyChainAttack via a #SideChannel to work is exponentially greater the more components I include.

That being said, #Linux distros are quicker to fix that than any #Windows or #macOS version ever will, because those have to maintain #Govware #Backdoors in order to be legal to sell and offer globally - espechally in places like the "P.R." #China...

And yes, @OS1337 doesn't come with #xz but it does utilize XZ for #Kernel and #initramfs compression, tho that's the algorithm and the Linux-own implementation...

@SweetAIBelle @starchy @OS1337

Yeah, I've barely built #mlb and sadly it seems like an abandoned project - I only pulled a fork so I can build the executeable and run it...

I also need to basically build everything except the FDD image, #linux #Kernel and mlb beforehand so I can just include the #initramfs.cpio into the kernel and finally shave ~ 200kB free...

Also thx for your continous contributions to OS/1337 ...

Si un jour, vous avez un message sibyllin au démarrage d'un PC sous Linux "BusyBox", "Enter help for a list of built-in commands. (initramfs)", PAS DE PANIQUE.

Commencez par taper "exit" à l'invite de commandes. Des informations sur la marche à suivre vont s'afficher. 1/2

Truc utile ?

* Problème : un système qui bug sur de nombreux logiciels surtout Firefox. Au reboot souvent une invite initramfs et besoin de réparer le système de fichiers.
Pour deux OS Ubuntu installés sur un même disque SSD

Ce qui marche depuis ce matin 🤞
* Dans l'UEFI rechercher SATA
* Remplacer le mode AHCI par Intel RST Premium with Intel Optane System Accelerator (RAID)
* Enregistrer et rebooter.

Je ne m'y connais pas assez pour vous dire pourquoi
