guix system seems not to respect ./pre-inst-env

guix system seems not to respect ./pre-inst-env

[John Darrington]

[-- Attachment #1: Type: text/plain, Size: 497 bytes --]

When I run:  ./pre-inst-env guix system disk-image gnu/system/install.scm

The resulting disk image is always the one corresponding to the currently installed guix,
not the one whose source is in .

How can I generate a disk image for an arbitrary guix?

That's odd.  It has always worked for me.  I can think of two possible
environment variables that could cause 'pre-inst-env' to fail:
"BASH_ENV" and "GUIX_PACKAGE_PATH".  Were either of these variables set
in the environment of the above command when it failed?

I think you have to do something like this:

(define guix-local
  (package
    (inherit guix)
    (source (local-file "path to guix local")))

(define guix-service-local
  (guix-service (guix-configuration (authorize-key? #t) (guix guix-local)))

and add guix-service-local to your installer.

Exactly.  ‘current-guix’ in (gnu packages package-management) is a
slightly more sophisticated version of that.

Hi John!

More precisely, the resulting image is for the Guix in your source tree,
*but* the image runs a version of Guix that is older than your source
tree; specifically, it runs ‘guix-devel’ from (gnu packages
package-management).

If you want the current Guix inside the image, you need to use
‘current-guix’ as done in (gnu tests install).

HTH!
