First, given a build like: https://releases-art-rhcos.svc.ci.openshift.org/art/storage/releases/rhcos-4.3/43.81.201911081536.0/x86_64/meta.json

Download the qemu image:
```
$ curl -L https://releases-art-rhcos.svc.ci.openshift.org/art/storage/releases/rhcos-4.3/43.81.201911081536.0/x86_64/rhcos-43.81.201911081536.0-qemu.x86_64.qcow2.gz | gunzip > rhcos-43.81.201911081536.0-qemu.x86_64.qcow2
```

Download new RPM or other content you want, in this case let's assume it's a new hyperkube we want to drop in `/usr/bin`:

`$ curl -L http://example/openshift-hyperkube-4.3.0-201912131246.git.0.09a9468.el8.x86_64.rpm | rpm2cpio | cpio -div`

I have a Lenovo P50 ThinkPad that I am issued at work.  I run the latest Fedora on my primary laptop for years but
have avoided running the NVIDA graphics drivers because installation was manual and could break with kernel updates.

I updated my personal Dell XPS 15 to use the new NVIDIA drivers that are now supported in Fedora 28 I think these were suppose to come from rpm-fusion but it looks like they are in Fedora 28 tree, I could be wrong.  The install was as easy as just installing the nvidia-driver package and reboot.  This worked without any issues.  I could launch nvidia-settings and glxgears without any issues.

The purpose of this Gist post is to document how I got the NVIDIA drivers from Fedora 28 on the P50.  It was not as easy as installing nvidia-driver and rebooting.  

For starters, here are the specs for the P50:

  [root@kwr50p kurtis] # inxi -SG

# Install ARCH Linux with encrypted file-system and UEFI
# The official installation guide (https://wiki.archlinux.org/index.php/Installation_Guide) contains a more verbose description.

# Download the archiso image from https://www.archlinux.org/
# Copy to a usb-drive
dd if=archlinux.img of=/dev/sdX bs=16M && sync # on linux

# Boot from the usb. If the usb fails to boot, make sure that secure boot is disabled in the BIOS configuration.

# This assumes a wifi only system...
