bug#59466: Kernel panic when installing with Ventoy

Hello,

It seems that I can't install Guix 1.3.0 with Ventoy. After starting installation from Guix GRUB, I get kernel panic. Ventoy works well otherwise with other distros.
Image checksum is good.

You can see the error in the attached image.

Thanks for your work,
Panos

Ventoy is not supported currently. It is up to them to add support for
Guix, not the other way around: we have some peculiarities with the boot
process that Ventoy completely ignores.  By the way, you should try
using the latest installer image instead of 1.3.0, as a lot of bugs have
been fixed since then.

Best,

Ah.  This is true of most dime-a-dozen ‘universal’ ISO booters, 
which merely source a GRUB .cfg and expect distributions to do all 
the work.  I'd shame them by name if they were memorable.  Guix 
indeed doesn't ‘support’ that!

Ventoy actually put some thought & effort into the process.  Like 
all clever hacks, there's some dependence on moon phase and luck, 
but it's not snake oil.

It injects some code into the boot process to expose the ISO file 
as a block device through Linux's device mapper.  Any distribution 
with dm-mod support, including Guix[0] (through dm-crypt), will 
see a ‘real’ block device straight from the kernel.  No distro 
cooperation is required beyond ‘please don't be too clever and 
peek behind the curtain’.  IME, Guix does not do so, and just 
works.

(So why does it fail here…?)

Kind regards,

Hi Panos,

Guix and Ventoy should work out of the box.

Thanks for including the exact panic message.  That's very 
helpful.

It's odd: Guix is trying to compile /ventoy/init as a SCM file.

- What is the sha256sum of the 1.3.0 ISO image you used?
- Could you try the ‘latest’[0] ISO and report the result?

Kind regards,

Poing!  If there's still some latent bug with Ventoy on your 
hardware, now's our last chance to debug it before the release.

[0]: But now with the 1.4.0rc2 image[1] and signature[2].

Kind regards,

Hi,

Please close this issue, it was fixed when I tried Ventoy with the latest image! Sorry for not letting you know earlier and thank you all for your work.

In freedom,

Panos
