The s6-fdholder-daemon program

s6-fdholder-daemon is a fd-holding daemon, i.e. a long-lived program. It listens on a Unix domain socket, then accepts client connections; it stores file descriptors on behalf of clients, along with an identifier for every file descriptor stored, and possibly an expiration date (after which the file descriptor will be forgotten). It also allows clients to retrieve a file descriptor by its identifier.
