Running your own local yum repo isn't all that hard as it turns out.

Allow building as a non-root user.
1. Make some important directories. I only care about powerpc packages, so I make the ppc and ppc64 directories, clearly if you use another architecture you should change that ;P
```
mkdir -p /home/user/rpmbuild/fedora/{BUILD,SOURCES,SPECS,SRPMS,tmp,RPMS/{noarch,ppc,ppc64}}
```
2. Now create a ~/.rpmmacros file. To use those directories you just created.
```
%_topdir        /home/user/rpmbuild/fedora/
%_builddir      %{_topdir}/BUILD
%_rpmdir        %{_topdir}/RPMS
%_specdir       %{_topdir}/SPECS
%_srcrpmdir     %{_topdir}/SRPMS
%_sourcedir     %{_topdir}/SOURCES/%{name}-%{version}-%{release}
%_tmppath       %{_topdir}/tmp
%_buildroot     %{_topdir}/%{_tmppath}/%{name}-%{version}-root
%packager       user@example.com
```
  With this there you can rpm -i src.rpm files, and run rpmbuild commands to generate RPMS (binary and source). I intend to have a bunch of packages on the go at any time so I use the %_sourcedir macro, have one directory per %{name}-%{version}-%{release}. You could just as easily do:
```
%_sourcedir     %{_topdir}/SOURCES
```
  It's easiest to decide upfront as changing will be a little cumbersome.
Make some RPMS. True this can be a little challenging at times but fortunately the packages I'm interested presented little challenge ... woot!
Fedora has a util for rummaging through RPMs and makeing the repodata files. It's called createrepo. So install that: yum install -y createrepo

I then moved all my locally built RPMS into a separate directory structure. I tried to make this look at least a little like real Fedora repos. Again I only care about powerpc, hence setting $basearch. You don't need to :). In case it isn't obvious I ran this script from the root directory of the repo (in my case /opt/yum).

#!/bin/sh

basearch=ppc
releasever=9
rpmbuild_base=/home/user/rpmbuild/fedora

for i in local local-debuginfo local-source ; do
        d="$i/$releasever/$basearch"
        [ ! -d $d ] && mkdir -p $d
done

find $rpmbuild_base/RPMS/  -type f \
	-exec /bin/cp {} ./local/$releasever/$basearch/. \;
find $rpmbuild_base/SRPMS/ -type f \
	-exec /bin/cp {} ./local-source/$releasever/$basearch/. \;
find ./local/$releasever/$basearch/. -type f -name '*debug*' \
	-exec /bin/mv {} ./local-debuginfo/$releasever/$basearch/. \;

for i in local local-debuginfo local-source ; do
        cd "$i/$releasever/$basearch"
        /usr/bin/createrepo .
        cd -
done

Setup apache to serve up that directory. This machine shouldn't need any other web services, so I just make / point at my /opt/yum directory

NameVirtualHost *
<VirtualHost *>
    ServerAdmin user@example.com
    DocumentRoot /opt/yum/
    ServerAlias host
    ServerName host.example.com
    ErrorLog /var/log/httpd/yum.repo-error_log
    CustomLog /var/log/httpd/yum.repo-access_log combined

    <Directory /opt/yum>
        Options Indexes
    </Directory>
</VirtualHost>

Now create a yum config you use this new goodness.

[local]
name=local $releasever - $basearch
baseurl=http://host.example.com/local/$releasever/$basearch/
enabled=1
gpgcheck=0

[local-debuginfo]
name=local $releasever - $basearch - Debug
baseurl=http://host.example.com/local-debuginfo/$releasever/$basearch/
enabled=1
gpgcheck=0

[local-source]
name=local $releasever - $basearch - Source
baseurl=http://host.example.com/local-source/$releasever/$basearch/
enabled=1
gpgcheck=0

If that all went well then:

[user@host ~]$ yum repolist
Loaded plugins: refresh-packagekit
repo id              repo name                                 status
fedora               Fedora 9 - ppc                            enabled
fedora-debuginfo     Fedora 9 - ppc - Debug                    enabled
fedora-source        Fedora 9 - Source                         enabled
local                local 9 - ppc                             enabled
local-debuginfo      local 9 - ppc - Debug                     enabled
local-source         local 9 - ppc - Source                    enabled
updates              Fedora 9 - ppc - Updates                  enabled
updates-debuginfo    Fedora 9 - ppc - Updates - Debug          enabled
updates-source       Fedora 9 - Updates Source                 enabled

and debuginfo-install and yumdownloader should do the right things woot!

There are probabluy all sorts of other cool things you can do here but this is enought to keep a few local machines in sync :)

Update: Type fixes, and add note about installign createrepo

So it's been a long time since I used RPM based distro "in anger", so I'm trying Fedora 9. First tips

yum check-update Check all enabled repositories for update and display them.
yumdownloader --source ${package} To grab the source RPM (*.src.rpm) for ${package}. You must have the appropriate source repositories configured and enabled. It's a shame that this isn't available (or did I missit) with the yum command.
Rename /etc/httpd/conf.d/welcome.conf to something that doesn't end in .conf once you've setup your web content. Otherwise you just get the std. "Welcome to Fedora" page.

Note: These may not be the best ways to get the job done but they worked for me

Update: fix typos
