Failed to start Remount Root and Kernel File Systems when booting r/o snapshot with overlayfs

[tillx4]

When I boot into a read-only snapshot using grub-btrfs-overlayfs I get some errors from systemd-remount-fs. Although the boot continues just fine and the snapshot is writeable as a temporary overlay filesystem. I am using Arch with kernel version 6.16.3.

Here is the relevant line from my /etc/fstab:

# /dev/nvme0n1p2
UUID=f50fe24b-d81c-43e0-b9c2-3f3957fae3f8	/         	btrfs     	rw,noatime,compress=zstd:3,ssd,discard=async,space_cache=v2,subvol=/@	0 0

Can I just ignore this error, because everything seems to be working fine or is there anything wrong?
If you need more information just let me know.
