Hey, I'm getting this error message when I'm trying to upgrade Omarchy. As far as I can see this affects snapshots not being done before upgrades and seems to be mounting the top level btrfs volume as /, instead of using an @ subvolume.
I have the / and /boot partitions on nvme0n1, and my /home on nvme1n1

Did you find a fix? I am about to move my home subvolume to another drive and don't want to mess up..

Still haven't found a fix for this. So if anyone can direct me to something useful I'd be grateful!

How did you install your system? ISO or manual install on top of arch?

#

If you did the latter: did you setup proper subvolumes in the archinstall step?
