What were you trying to do that didn't work?

Installation of bootc-enabled container image using Anaconda on a system with multiple disks fails:

INFO:program:Running... bootc install to-filesystem --bootloader=grub --karg=resume=UUID=6de9dc03-a
127-4c21-8454-cee7ae3a524d --karg=rd.lvm.lv=rhel/root --karg=rd.lvm.lv=rhel/swap --stateroot=default --source-imgref=r

DEBUG:anaconda.modules.payloads.payload.rpm_ostree.installation:bootc output: error: Installing to filesystem: Found multiple parent devices /dev/vda and /dev/vdb; not currently supported

What is the impact of this issue to you?

It may limit the installation user experience, as opposed to the advanced partitioning options with other installation payloads (e. g. packages). It also makes the installation more difficult even if the user decides to use only one disk, as in such a case, it's necessary to instruct Anaconda to ignore all but one selected drive using ignoredisk --only-use=/dev/vdX or create the entire partitioning manually instead of using autopart which defaults to LVM on CentOS/RHEL.

Please provide the package NVR for which the bug is seen:

bootc-1.10.0-2.el10

How reproducible is this bug?:

100%

Steps to reproduce

1. Start RHEL-10.2 installation on a machine with multiple storage devices using bootc kickstart command to install a bootable container image.

Expected results

It's possible to create partitioning spanning multiple storage devices (LVM, RAID).

Actual results

Installation fails, because installation on partitionings spanning multiple storage devices is not yet supported by bootc.
