Reviewer's Guide

This PR enhances the createdisk.sh script to support 9P file sharing on Windows by adding steps that enable a COPR repository and download the 9pfs binary via SSH when generating the Windows bundle, then include it in the installation list.

Walkthrough

The script createdisk.sh was modified to add a conditional block that, when generating a Windows bundle, enables the COPR repository mskvarla/9pfs, downloads the 9pfs package locally, disables the COPR repository, and appends 9pfs to the list of additional packages for installation on the VM.

Changes

File(s) Change Summary
createdisk.sh Added conditional logic for Windows bundle generation to enable COPR repo mskvarla/9pfs, download 9pfs package locally, disable the repo, and append 9pfs to additional packages.

Poem

In the land of scripts, a new path is spun,
For Windows bundles, more work is done.
The bunny hops to COPR’s door,
Fetches 9pfs and packages galore.
Into the VM, the bundles flow—
A disk creation tale only bash bunnies know! 🐇💻

/hold

This adds a Dockerfile that is used to create a container in which
the 9pfs binary is built. The binary is then extracted and installed
into the system for 9p file sharing.

Removed the container-compilation process and changed it to simple
installation from a custom COPR repository that contains the binary.

What is our plan around it, always going to use the copr or it is just for initial POC side? As per https://download.copr.fedorainfracloud.org/results/mskvarla/9pfs/srpm-builds/09226159/9pfs.spec file looks like we are just building the binary, can we migrate to container image for this which can be built on brew internally?

Initially yes, I think the COPR repo should be enough to have this merged, after we see it works, we can move to brew.
