There are not many files on the filesystem in the ubuntu-core case, period;
the only one we've needed to delete, so far, is one that snap prepare-image
will soon stop writing, once cloud-init's ds-identify support has landed. I
don't think we should expect this to be an ongoing production use case for a
hook.
