+In Fedora we use systemd for starting services. We need to finish starting

+process of <command>ypbind</command> service not before service is fully

+started, which means <command>ypbind</command> daemon is prepared to answer.

+There is a test script <filename>/usr/libexec/ypbind-post-waitbind</filename>

+used in ypbind.service, that waits for <command>ypbind</command> daemon to be

+fully connected to NIS server and waits by default up to 45s.  Sometimes this

+is not enough, because network set up can take longer than 45s during boot, so

+starting ypbind.service fails. User can increase the timeout by setting an

+environment variable NISTIMEOUT in <filename>/etc/sysconfig/ypbind</filename>.

+For example NISTIMEOUT=180 means <command>ypbind</command> will wait up to 180

+seconds for binding to a NIS server.  Another option is to enable

+NetworkManager-wait- online.service, which will make <command>ypbind</command>

+to wait until network is properly set up.

+In case something needs to be changed in the ypbind.service, it is adviced not

+to change the ypbind.service directly, but rather to create a new file under

+<filename>/etc/systemd/system/ypbind.service.d/</filename>, i.e. if we need to

+start <command>ypbind</command> before service foo.service, we can create file

+<filename>/etc/systemd/system/ypbind.service.d/wait-foo.conf</filename> with

+the following content:

+If you need to pass other arguments to <command>ypbind</command> daemon withing

+systemd unit file, you can set these arguments as OTHER_YPBIND_OPTS environment

+variable in <filename>/etc/sysconfig/ypbind</filename>. For example in order to

+set a fixed port <command>ypbind</command> should run on, you can specify

+OTHER_YPBIND_OPTS="-p 876" in <filename>/etc/sysconfig/ypbind</filename>.
