Thanks for mentioning it. Yes, that's also a way to do it. It seems a
bit more complicated to set up (all files must be in a common "merge"
directory) and does not seem to support sub-directories (-maxdepth 1),
so it is a bit less flexible than the ROOTFS_DEBUG_FILES that I was
proposing. On the other hand, the files get packaged properly (well, if
one is careful about adapting the default MIT license as needed).
For my use case, I still prefer the quick-and-dirty approach.
