The quagga-0.96.3-netlink.patch is no longer needed, it has been included in a
Quagga release since 0.96.5.  See:

http://cvs.quagga.net/cgi-bin/viewcvs.cgi/quagga/zebra/rt_netlink.c.diff?r1=1.15&r2=1.16

quagga-0.98.2-gcc4.patch does not appear to be necessary either, I received no
warnings or error messages when I left the patch out of a test build (FC6 i386).

both patches were removed. There is also new version available on rawhide
(quagga-0.99.6-1.fc7)

I've modified spec file to be Packaging Guideline compliant and rpmlint a bit more silent. There is explanation to rest of E & W of rpmlint:

For example:
  #zebra_spec_add_service ospfapi  2607/tcp "OSPF-API"
is imho out-of-date, as /etc/services lists
  connection      2607/tcp                # Dell Connection
instead.

+ MUST: package named according to the Package Naming Guidelines

+ MUST: The package must meet the Packaging Guidelines .
+ MUST: The package licensed with a Fedora approved license and meets the Licensing Guidelines
+ MUST: The License field in the package spec file matches the actual license
+ MUST: If (and only if) the source package includes the text of the license(s)

= MATCHES

+ MUST: The package successfully compiles and builds into binary rpms on at
least one primary architecture
 - tested on x86_64, no problems
0 MUST: If the package does not successfully compile, build or work on an
architecture, then those architectures should be listed in the spec in
ExcludeArch
+ MUST: All build dependencies must be listed in BuildRequires, except for any
that are listed in the exceptions section of the Packaging Guidelines
0 MUST: The spec file handles locales properly. This is done by using the
%find_lang macro
0 MUST: Every binary RPM package (or subpackage) which stores shared library
files (not just symlinks) in any of the dynamic linker's default paths, must
call ldconfig in %post and %postun.

%define		_libdir		%{_exec_prefix}/%{_lib}/quagga
%files
%{_libdir}/*.so.*

It's not in linker's default paths, so I believe there is no need to run ldconfig.

0 MUST: Packages must NOT bundle copies of system libraries
+ MUST: If the package is designed to be relocatable, the packager must state
this fact in the request for review, along with the rationalization for
relocation of that specific package. Without this, use of Prefix: /usr is
considered a blocker
+ MUST: Package must own all directories that it creates. If it does not create
a directory that it uses, then it should require a package which does create
that directory
+ MUST: Package must not list a file more than once in the spec file's %files
listings
+ MUST: Permissions on files must be set properly. Every %files section must
include a %defattr(...) line.
+ MUST: Each package must have a %clean section, which contains rm -rf
%{buildroot} (or $RPM_BUILD_ROOT).
+ MUST: Each package must consistently use macros
+ MUST: The package must contain code, or permissable content
+ MUST: Large documentation files must go in a -doc subpackage
+ MUST: If a package includes something as %doc, it must not affect the runtime
of the application
+ MUST: Header files must be in a -devel package
0 MUST: Static libraries must be in a -static package
0 MUST: Packages containing pkgconfig(.pc) files must 'Requires: pkgconfig'
+ MUST: If a package contains library files with a suffix (e.g. libfoo.so.1.1),
then library files that end in .so (without suffix) must go in a -devel package
+ MUST: devel packages must require the base package using a fully versioned
dependency: Requires: %{name} = %{version}-%{release}
+ MUST: Packages must NOT contain any .la libtool archives, these must be
removed in the spec if they are built
0 MUST: Packages containing GUI applications must include a %{name}.desktop
file, and that file must be properly installed with desktop-file-install in the
%install section
+ MUST: Packages must not own files or directories already owned by other
packages
+ MUST: At the beginning of %install, each package MUST run rm -rf %{buildroot}
(or $RPM_BUILD_ROOT)
+ MUST: All filenames in rpm packages must be valid UTF-8

All MUST things passed.


I need just one clarification before I'll set review+ :

qugga.spec:226: # /etc/services is already populated, so skip this

So there is /etc/services dependency, shouldn't we set Requires to setup package as well?
$ rpmquery --whatprovides /etc/services
setup-2.8.20-1.fc13.noarch

I've added requirement for /sbin/chkconfig in post and preun sections and corrected section for requires /sbin/install-info.
Commited in rawhide.

why you don't build quaga for fedora-epel ?

(In reply to comment #7)
> why you don't build quaga for fedora-epel ?

Quagga is in RHEL therefore is not in EPEL.
