For the use case we are talking about here, locally-generated initrds, mkosi-initrd is not intended in the first place. Dracut will remain around for that for the foreseeable future in all distros.

mkosi-initrd’s use case is pre-built initrds, and we already have a solution for that: core-initrd and snapped kernels, as used on FDE desktop images.

mkosi-initrd is used also fully intended to be used for locally built initrds. The image will be customized for local crypttab, cmdline, modules, firmware, but still be built from packages for all the rest. I have documented this some time ago at https://wiki.debian.org/EFIStub#With_mkosi-initrd

While you can do that it’s not advisable due to the significant overhead involved.

[bluca]

Building from packages is for sure a bit slower due to dpkg, but I wouldn’t say it’s a deal breaker

I use dracut in ubuntu since 22.04, I never had single problem, it is powerful and easy to config.
I actually installed the dracut binary package, and removed initramfs-tools. I do not want hybrid config. I think it works more stable without initramfs-tools

@YamiYukiSenpai

I’m not sure if this is related to dracut

I asked around; are you using the Rust coreutils instead of the regular one?

If so, GRUB’s packaging isn’t quite adapted for it yet. You could either revert to the regular coreutils, or try patching it manually (not recommended).

If you aren’t actually using the Rust coreutils, then this is very curious, please explain more.

[YamiYukiSenpai]

Oh! that could be it…

Haha

That doesn’t show after I reverted it

Does clevis-dracut work in 24.10? It doesn’t seem to work in 24.04, although it was strangely working for me until a recent update.

I need Clevis to connect to a Tang server.

I notice that clevis-dracut seems to be supported in 25.04.

Dracut will be supported in Ubuntu 25.04

Following Please try out dracut and the specification [Spec] Switch to Dracut we are going to support Dracut as alternative to initramfs-tools as initrd generation tool in Ubuntu 25.04 (plucky). We want to make Dracut the default in the following Ubuntu 25.10. How to switch to Dracut If you are running Ubuntu 25.04 (plucky) you can decide to switch from initramfs-tools to Dracut. The following steps are designed to be easy and safe to revert back. Check the ‘Known Issues’ section if your set…

Thanks

@uma-jay

Does clevis-dracut work in 24.10?

25.04 releases this Thursday. Upgrade when it’s offered (usually a week or two after release) and try it after you’ve upgraded if you want to experiment with it for best results.
