The reason 'guix build foo' gives a different result is because you have not run 'guix pull', so you are using the "guix snapshot" from gnu/packages/package-management.scm, which is on a fixed commit. Whereas when you built the VM, you were likely using a newer version of Guix. > How to properly export local definitions in the > virtual machine image ? There are a couple of ways around this. One is to run 'make update-guix-package' in the Guix source tree to update the Guix snapshot, and use './pre-inst-env' when generating the VM. It requires a Guix development setup though. Another is to look at the commit that was used to generate the VM in /run/current-system/provenance and run 'guix pull --commit=that-commit'. Perhaps 'guix system vm-image' could learn a '--update-guix-snapshot' to automatically update the "system guix". Someone would have to implement it first though. :-) HTH, Marius signature.asc Description: PGP signature
Local definitions and Virtual machine image
Hello Guixers ! I created an image with 'guix system vm-image' which contains local defined packages. These packages are present on the Virtual Machine however they are not listed with 'guix package --list-installed'.As I need to customize LD_LIBRARY_PATH, I use "guix build" to list store directories from package names but it tries instead to recompile them even though they are already installed. How to properly export local definitions in the virtual machine image ? Best regards, Emmanuel Medernach
