I like it! Is it intended to replace gnu/system/examples/vm-image.tmpl? The phrase "live image" suggests a live USB stick that can be booted as a live system. To avoid confusion, would it be better to just call it a "VM image"? I don't feel that strongly about it. > (define this-file > (local-file "./vm-live.tmpl" "config.scm")) Cute! But FYI, I tried building this and it failed at first, since I renamed the file and forgot about this reference. I then re-ran the command from the same directory as the file, which of course worked. I built it, booted with 1 CPU and 1024 MB of RAM, logged in, and successfully built GNU Hello. I confirmed that changes persist across reboots, and that the file system appears to have about 16 GB of space left. When I booted into the system, I noticed some things: - There are many folders on the desktop. For example, there is one for "/sys/fs/cgroup/memory". A minor blemish, but rather odd. - The "guest" user cannot run "sudo". However, after you invoke "passwd" and change the password to something, you can invoke sudo. I guess this is a side effect of using an empty password. Would it be hard to arrange for the "guest" user to be allowed passwordless sudo? I guess I should have listened to your comment in the config file and given root/guest a password from the start! - "sudo herd status" reports that term-auto and user-homes is stopped, which I think might be intended, but I'm not sure. I also see possibly unnecessary services: wpa-supplicant, upower-daemon. The VM probably doesn't need wpa-supplicant, but maybe it needs upower-daemon? Not sure. - There is a "Web Browser" link at the bottom of the screen. It begs to be clicked. But when you click it, the system asks you to choose a default web browser, and there are no options. Hmm. - "sudo guix system reconfigure /etc/config.scm" failed because "error: missing field initializers (home-directory)". I then ran "guix pull" and tried again with "sudo -E guix system reconfigure /etc/config.scm", since I remembered that the proper way to do this using my freshly pulled Guix would be to use -E. I got a new error: "error: device '/dev/vda' not found: No such file or directory", which occurred because the VM has /dev/sda but not /dev/vda. Maybe we can modify the config file to use sda instead? I hope that helps. I think it's better to provide a VM image than none at all. Even though it's a little bumpy, it's still a decent way to try out Guix if you don't want to install it on your existing distro. -- Chris
