Home fails to mount 'not canonical' - btrfs filesystem | Bazzite | rpm-ostree

Hi,

Please help me debug this issue. I have a fresh Bazzite install that is failing to boot and dropping into emergency mode. It appears to be a problem with mounting the Home directory but I cannot for the life of me work out the issue and cannot find any reference to it on Google at all.

Error:

This btrfs partition can be mounted just fine manually:

(130)(deck@steamdeck tmp)$ sudo mount -t btrfs -o subvol=02,compress=zstd:1 UUID=a1f467d0-d033-4a49-ab12-62e6388ddc16 /tmp/bazhome
(deck@steamdeck tmp)$ cd /tmp/bazhome/
(deck@steamdeck bazhome)$ ls
seb
(deck@steamdeck bazhome)$

Thanks!

You would be better served asking the Bazzite folks on their Discourse forum :

The reason I say this, is because if it’s a bug in their build they should know about it and hopefully fix it. If it’s not, they can still give you more direct support.

Removed installation

Added rpm-ostree

Agreed.
Note that Bazzite seems to use numeric subvol names (00, 01, and 02 are examples) while fedora uses a literal name (root, home, var, etc.) This may not impact the question, but since it is related to mounting subvolumes it might.
