overlay modules to a lib that is a symlink
When LAVA overlays the modules.tar.xz file, on a rootfs that have "/lib" as a symlink, tar overrites the /lib dir too. Before the tar operation: /lib -> /usr/lib/... after the tar operation /lib/modules only, and /lib is a directory not a symlink.
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
