# 2. O LINK .LATEST (Rigorosamente conforme NVIDIA/VirtualBox)
# O akmods espera o link dentro de /usr/src/akmods apontando para o arquivo no mesmo diretório

# NOTA: O arquivo .src.rpm já é instalado aqui pelo seu pacote 'google-coral-kmodsrc'.
# Criamos o link relativo para evitar erros de path absoluto.

# 3. EMPACOTAMENTO DOS ARQUIVOS (Resolvendo o erro de unpackaged)
# Como o kmodtool do Fedora não aceita '%files -n' duplicado, usamos a macro interna.
