You read my mind. A union type record with a label is not optimal, much better to have separate records with semantically clear names.

Thanks Daniel and Ludovic for the helpful information. I will try to install again over the coming days and report my progress.

Could someone help me with the basics necessary to complete this installation? Also, does anyone have advice on what to do when GuixSD is booting, has issues, and then drops into a scheme@(guile-user) prompt? I'm at a loss. I've used this command to produce a partition table file: --- parted -ms /dev/disk/by-id/ata-WDC_WD20EURS-63SPKY0_WD-WMC300539593 print --- Here is the layout, given by the output of the parted command shown above: BYT; /dev/sdg:2000GB:scsi:512:4096:gpt:ATA WDC WD20EURS-63S:; 1:1049kB:11.5MB:10.5MB:::bios_grub; 2:11.5MB:53.7GB:53.7GB:linux-swap(v1)::; 3:53.7GB:2000GB:1947GB:ext4::; First this shows a 10 MB BIOS GRUB partition, which unless I'm mistaken, is the preferred way to setup GRUB on a GPT disk on a system that's Legacy-BIOS-Only / non-(U)EFI. Second there is a 50 GB swap partition. It's labelled swap. Yes, I know that seems like a lot, but this machine I'm installing on is a server capable of housing lots of RAM. I don't imagine it would be practical sifting through 50GB of core dump to fix a bug, but the entire disk is 1.8 TB, so why not? Third / finally is the ext4 root partition. It's labelled root and takes up the rest of the 1.8 TB disk. This machine itself houses 8 disks. I felt like using /dev/disk/by-id/ made more sense. Here is my config.scm that I ran guix system init with: (use-modules (gnu)) (use-service-modules networking ssh) (use-package-modules admin) (operating-system (host-name experiment0) (timezone America/New_York) (locale en_US.UTF-8)Also ;; Assuming /dev/sdX is the target hard disk, and root is ;; the label of the target root file system.
