Overriding content in an old RHCOS AMI for testing

	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`

NVIDIA on Lenovo P50 and Fedora 28

	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:

Minimal instructions for installing arch linux on an UEFI system with full system encryption using dm-crypt and luks

	# 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...
