_POSIX_SPAWN

A spawned child is a new process running a prelinked executable image: the path (or file) argument is resolved by the application-provided posix_spawn_image_lookup() registry rather than loaded from a file system.

posix_spawnp() searches a file without a slash along PATH, or along CONFIG_POSIX_DEFAULT_PATH when PATH is unset, for an executable regular file in the file system; prelinked registry images are named by their full path.

Enable this option with CONFIG_POSIX_SPAWN.
