postmarketOS support #1615
Description
Is your feature request related to a problem? Please describe.
This is a new issue (AFAIK).
Describe the solution you'd like
postmarketOS (pmOS) is a mobile-centric Linux distribution based on Alpine Linux intended to provide a fully-free operating system for mobile. pmOS has a generic installer for x86 machines that we can pull from the servers however it is xz-compressed so we might have to be a lil creative with using it.
Describe alternatives you've considered
Ventoy with VHD2ISO is a viable alternative but it's not a tenable solution at the moment.
