Re: Validating/repairing guix system install

[Steve George <steve@futurile.net>]

Hi Kevin,

The existing system's configuration is in /run/current-system/configuration.scm. Might be worth inspecting this and seeing if there are obvious mistakes.

The installer places a copy of this in /etc/config.scm. This is the one that users normally start by editing. To validate that it's correct the manual suggests that you do this:

  # creates a vm start-ups script
  guix system vm /etc/config.scm

  # start the vm - login root/no-password - check through
  /gnu/store/...run-vm.sh

If you're able to start the VM correctly then you can apply that configuration.

Normally you'd go back a generation to an earlier 'known good' configuration, but it sounds like you don't have one. Maybe also check that your hard drive is OK and that the Store doesn't have problems:

  guix gc --verify=contents

Bits of the manual that may help:

https://guix.gnu.org/manual/devel/en/html_node/Getting-Started-with-the-System.html
https://guix.gnu.org/manual/devel/en/html_node/Chrooting-into-an-existing-system.html

Good luck,

Futurile / Steve
