Various software relies on an always resolvable local host name. When using dynamic hostnames this is usually achieved by patching /etc/hosts at the same time as changing the host name. This however is not ideal since it requires a writable /etc file system and is fragile because the file might be edited by the administrator at the same time. nss-myhostname simply returns all locally configured public IP addresses, or -- if none are configured -- the IPv4 address 127.0.0.2 (wich is on the local loopback) and the IPv6 address ::1 (which is the local host) for whatever system hostname is configured locally. Patching /etc/hosts is thus no longer necessary. Note that nss-myhostname only provides a workaround for broken software. If nss-myhostname is trigged by an application a message is logged to /var/log/messages. Please check whether that's worth a bug report then. %prep %setup -q %patch0 -p1 %build autoreconf %configure --libdir=/%{_lib} --with-warning make %{?_smp_mflags} %install make DESTDIR=%{buildroot} install install -D -m 755 %SOURCE1 %{buildroot}%{_sbindir}/nss-myhostname-config rm -rf %{buildroot}/usr/share/doc/nss-myhostname %clean rm -rf $RPM_BUILD_ROOT %preun if [ "$1" -eq 0 -a -f /etc/nsswitch.conf ] ; then %{_sbindir}/nss-myhostname-config --disable fi %post -p /sbin/ldconfig %postun -p /sbin/ldconfig %files %defattr(-, root, root) %doc README %doc LICENSE %{_sbindir}/nss-myhostname-config /%{_lib}/* %changelog ++++++ 0001-optionally-warn-if-nss-myhostname-is-called.diff ++++++
