ypserv bug fix update

An updated ypserv package that fixes various bugs is now available.

The Network Information Service (NIS) is a system that provides network
information (login names, passwords, home directories, and group
information) to all machines on a network. NIS allows users to log in on
any machine on the network, as long as the machine has the NIS client
programs running, and the user's password is recorded in the NIS password
database. NIS was formerly known as Sun Yellow Pages (YP).

This updated package fixes the following bugs:

* in the previous ypserv package, ypserv logged a lot of common errors
that are safe to ignore. In this updated package, the verbosity of ypserv
logs has been decreased for certain common errors.

* some binaries -- mainly ypserv -- were stripped of debugging symbols,
even though a debuginfo package was available. In these cases, no debugging
symbols were available when using gdb.

* in the previous ypserv package, "/var/yp/Makefile" did not fail when the
NIS/YP domain name was set to "none". This was seen by running the "make -C
/var/yp" command. Now, for these situations, the "make -C /var/yp" command
fails, and an error occurs.

Users of ypserv are advised to upgrade to this updated package, which
resolves these issues.

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
