Unable to install on a raid using anaconda

[duritong]

I am trying to install a fedora 41 bootc through anaconda on raid-devices.
I have a test setup using VMs to mimick what will be on real-baremetal.

The installation procedure works if I do not configure raid devices in anaconda. As soon as I start configuring raid devices it fails to install the bootloader

It fails with the following error message from the anaconda package log:

DEBUG:anaconda.modules.payloads.payload.rpm_ostree.installation:Adding --update-
firmware to bootupdctl call
INFO:program:Running in chroot '/mnt/sysroot'... bootupctl backend install --aut
o --write-uuid --update-firmware --device /dev/vda /

The kickstart file I try to use is:

As you might notice I try to have dedicated /boot and /boot/efi partitions, since eventualyl I'd like to use luks to encrypt my root filesystem. However, I first wanted to make sure I can have a bootable system with raid, before diving into the luks part.

I had different variants on how to configure the raid, but eventually, it always failed with the same issue when installing the bootloader.
