It turns out OverlayFS doesn't handle gracefully when the same source is specified multiple times in lowerdir= and it fails with ELOOP: Failed to mount overlay (type overlay) on /run/systemd/mount-rootfs/opt (MS_RDONLY "lowerdir=/run/systemd/unit-extensions/1/opt:/run/systemd/unit-extensions/0/opt:/run/systemd/mount-rootfs/opt"): Too many levels of symbolic links This happens even if we mount each image in a different internal mount path, as OverlayFS will resolve it and look for the backing device, which will be the same device mapper entity, and return a hard error. This error does not appear if dm-verity is not used, so it is very confusing for users, and unnecessary. When mounting ExtensionImages, check if an image is dm-veritied, and drop duplicates if the root hashes match, to avoid this user-unfriendly hard error. |
