C100P - Cadmium Arch EMMC Installation Fails

[TheNathan0]

After figuring out some kind of a workaround on getting WiFi to work on Cadmium Arch (on C100P) (C100P - Cadmium Arch WiFi Broken By Default (Needs Workaround) #133 did I find a new issue.

Installing to the SD card functions as it should, but installing to the internal EMMC does not work at all.
Sway appears to be a bit broken. Could be something I did though, but I think it might be something related to install script?

Running the install script gives:

Welcome to Cadmium installer
Choose your fate:
1. Installation to internal memory
2. Installation to this medium
3. Drop to shell
:

Selecting the first option shortly then after gives:

WARNING: Primary GPT header is being ignored
ERROR: I/O error when trying to write primary GPT

The script then stops afterwards.
The last version of Cadmium that I've ever had working with installation to internal EMMC was version 0.3.0, could this likely be due to the cgpt that it uses? install fail on Asus C201PA (speedy) #127

Might look into ripping cgpt from ChromeOS and seeing if that makes a different on installing to EMMC.

Later edit: Arch runs okay-ish when it is stable, but I've had some issues here and there with stability. GPU acceleration is there, but even Webrender enabled Firefox tends to be a struggle for it at times. Maybe it isn't the best time for Arch on Veyron Minnie at the moment. It was tested on the SD card.
