If the distros are from the same family, ie RHEL/CentOS/Fedora, then it
is pretty safe to use 1 repo for the family.

You will need to separate the different architectures though i386/x86_64.

My repo directories are setup like such:

<Repo Name>
    +- SRPMS
    +- i386
    |    +- RPMS
    +- x86_64
         +- RPMS

Then in i386 I run 'createrepo' (of course install createrepo first!),
and in x86_64 I run 'createrepo'.

Then I just create a simple <Repo Name>.repo file /etc/yum.repos.d
like such:

[Repo Name]
name=Repo Name Packages for Linux
baseurl=http://software/Software/Repo Name/Linux/$basearch

I leave setting up Apache as an exercise in well, setting up Apache.

Hint: Setup mime type .rpm as text/plain otherwise rpm chokes.

Afterwards you could get fancy and create an RPM with the .repo
file in it, and/or setup gpg keys for signing your RPMS.
