Only server is the required argument for glfs_set_volfile_server and both transport and port are optional. When glfs_set_volfile_server is invocated multiple times, only on the first invocation we replace port 0 with 24007 and transport NULL with "tcp". Hence, replacing the parameters at the entry function is the right way.
