What exactly did you do ? command line or gui ?
Add remove programs or update system ?

>> - especially yum and/or PackageKit?
wget 
http://download.fedora.redhat.com/pub/fedora/linux/updates/9/i386.newkey/yum-3.2.20-5.fc9.noarch.rpm
wget 
http://download.fedora.redhat.com/pub/fedora/linux/updates/9/i386.newkey/yum-metadata-parser-1.1.2-9.fc9.i386.rpm
wget 
http://download.fedora.redhat.com/pub/fedora/linux/releases/9/Fedora/i386/os/Packages/pygpgme-0.1-8.fc9.i386.rpm

rpm -Uvh *fc9*.rpm

if further requirements are missing download them also from similar to 
the above urls.

Once yum is working, it can do dependency resolution and downloading 
again, so just yum install [list of each package that got deleted]

- boot CD/DVD
- Escape as the boot countdown is running.
- append rescue to the kernel command
- yes, yes, yes. (you want networking, mount your system)
- this gets you to a state where your original system is mounted under:
/mnt/sysimage/
- make some network settings (if not auto set).
- yum --installroot=/mnt/sysimage install yum

[without having such a dead system here to confirm exactly].

Was this the complete set of transactions that occurred on this day ?
If you didn't fu, then something is seriously amiss here.

Nasty.

The rescue CD already has that.

Yes.

- go to friends computer, ask on a list...
- type yum remove some files in your list.
- no, don't do it
- note all the packages that it wants to remove.
- download each from either the current version from either releases or 
updates-newkey.
- rpm -Uvh the lot of them.
