Look for a hook script in any config/images/rauc-hooks.sh in the usual search locations, and if one is found, package it into the RAUC bundle and reference it in the manifest. Otherwise leave the [hooks] section in the manifest empty.
As hooks that should be called by RAUC need to be mentioned in the manifest too (in the relevant slot or the [bundle] section), the image config will still need to be forked by BSPs in order to adapt the manifest for that use case. However, the mechanism to find the hook script is then already in place, and can be used as-is.
