But in this case, I'm not entirely sure it is needed...

(Since I'm doing this on my laptop right now...)

If you are running Fedora, the Right Way would be to install their apt
package.

  rpm -Uvh http://download.fedora.us/fedora/fedora/1/i386/RPMS.stable/apt-0.5.15cnc1-0.fdr.3.1.i386.rpm

I probably need to start mirroring download.fedora.us until all that
content is moved to download.fedora.redhat.com.  In the mean time, use
the default /etc/apt/sources.list (make sure it is the new one
pointing to download.fedora.us) or do like it says and point to a
mirror site.

Next you'll probably want to enable the non-US repository.  Just
create /etc/apt/sources.list.d/livna.list with the following contents:

rpm http://rpm.livna.org fedora/1/i386 stable
rpm-src http://rpm.livna.org fedora/1/i386 stable

You'll also need to manually add the livna GPG key since the Fedora
apt package bails out if it can't verify the signature on a package.
Just do the following:

  cd /etc/apt/gpg
  wget http://rpm.livna.org/RPM-LIVNA-GPG-KEY
  rpm --import RPM-LIVNA-GPG-KEY

At this point, you should be able to "apt-get update && apt-get
upgrade".

You *should* be able to avoid that problem, even using freshrpms, by
putting the following in your /etc/apt/preferences:

Package: *
Pin: release c=os
Pin-Priority: 1001

That should make apt always prefer the "core" packages, to the point
that it will downgrade packages if necessary.  Setting Pin-Priority to
991 should keep it from ever installing new packages from other
sources, but won't make it downgrade packages.

If you wanted to get really crazy, you could pin "c=stable" slightly
lower than "c=os" (but above 990), so that the fedora.us packages are
preferred over the freshrpms packages.  That should make it fairly
safe to always point to the freshrpms repository.

At least that's how I understand it from reading the
apt_preferences(5) man page.  I haven't actually tested this yet...

Oh, and if anyone wants to pull freshrpms stuff off our ftp site, use
the following /etc/apt/sources.list.d/freshrpms.list:

rpm http://ftp.kspei.com/pub/freshrpms/ayo fedora/linux/1/i386 freshrpms
