Description André 2020-10-11 01:08:11 UTC 
Description of problem:

When installing fedora silverblue 33 beta with the partitions as follows, grub will give some errors and the system won't load:

/boot/efi efi partition

btrfs volume:
/ - root, btrfs subvolume
/boot - boot btrfs subvolume
/home - home btrfs subvolume

By moving /boot to a dedicated btrfs partition, not subvolume, the system does boot.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Create manual partitions as in the description.

Actual results:

Grub shows error messages and system doesn't boot.

Expected results:

System should boot.

>Grub shows error messages and system doesn't boot.

Can you be more specific? This does work with Custom partitioning. Did you use Advanced-Custom partitioning? Can you be more specific  with your "steps to reproduce"? There's not enough information here to try to reproduce this and figure out where the problem is. What Fedora image did you use? The exact filename of the ISO please.

Yes, I did use Advanced Custom BLIVET GUI and the name of the iso is "Fedora-Silverblue-ostree-x86_64-33_Beta-1.3.iso" the steps I took can bee seen on the uploads I made, let me know if you need anything else.
Comment 6 Chris Murphy 2020-10-11 21:00:55 UTC 
OK so the problem here is that rpm-ostree doesn't currently support /boot on the same file system as /. There are upstream patches to make it supported, but right now /boot must be a separate file system (ext4 or btrfs). It's not sufficient for it to be a separate subvolume on the same file system as /.
