[Alma9] Labeled disk cannot be mounted

[cap10m0]

Hi guys,

I've been customizing an AlmaLinux ISO within Anaconda for some time. Everything was working fine when I tried to install the ISO using Ventoy while I was on AlmaLinux 8.

However, since switching to AlmaLinux 9, I am no longer able to install my ISO using Ventoy (it still works fine with other tools like Rufus).

For Anaconda to work, it needs access to the installation sources. To achieve this, I use a disk label:

append initrd=initrd.img inst.stage2=hd:LABEL=TEST inst.ks=hd:LABEL=TEST:/ks/ks.cfg nomodeset quiet

Since switching to the AlmaLinux 9 ISO, the label cannot be mounted when I start it with Ventoy:

10:14:25,914 DBG modules.payloads.payload.dnf.dnf_manager: The DNF cache has been cleared. 10:14:26,929 ERR payload.manager: PayloadError: Could not mount device specified as /dev/disk/by-label/TEST 10:14:26,929 DBG payload.manager: Updating payload thread state: ERROR

Any ideas?

Thank's.
