Hi Guix! I was surprised to find out that $ guix system image and pals only support a small subset of the file systems Guix has available. (ext2-4, vfat, and fat32)
What's more, even if an alternative file system is supported (it's not) changing the root filesystem format alongside an operating-system is a fairly involved process. By default, image constructors seem to ignore the file-system field of an operating system when generating partitions and formatting them. I think the following changes would be ideal: 1. Add more make-*-image functions to gnu/build/image.scm to support common file systems people would want to use. 2. Capture the root filesystem type from an operating-system record and use it when generating the root filesystem partition on the image. It's not always possible to manually partition disks and run guix system init (cloud providers, efi bootloader installation on sbcs) ahead of time on an external machine, so I feel there is a valid use case here. If nothing else, I'd like a warning to be emitted if an operating-system's file-system structure does not match what $ guix system image generates. -- Take it easy, Richard Sent Making my computer weirder one commit at a time.
