More patches on the way for improving .list_exports signature and adding .export_description, but this is the promised code showing why nbdkit_string_intern is useful. Patch 4 is somewhat RFC: we could either add new API to take the boilerplate from: foo_config(const char *key, const char *value) { if (strcmp (key, "file") == 0) { CLEANUP_FREE char *tmp = nbdkit_realpath (value);

This is a revision of my .default_export work, plus new work on .export_descriptions and a new exportname filter. I think it is now ready to check in. Things I'd still like in 1.22: - the file plugin should implement .list_exports (patch already posted, but it needs rebasing on this series) - the ext2 filter should override .list_exports when in exportname mode - the nbd plugin should be
