RH 6.0, upgraded from Mandrake 5.3

On system startup, in the file /etc/rc.d/init.d/ypbind called with argument
'start' the ypbind daemon only connects to the servrer, which is up at the
moment the ypbind daemon is run. The delay loop added afterwards
does not cause the ypbbind daemon to retry.

Solution:
(a) force running ypbind daemon to reread it's configuration and retry
     search for master,
(b) increase the time between the retries or the number of retries, or both.

Please, find below the appropriate excerpt from my corrected file.
I expressely grant you the right to use this code section in your
