Sourcing environment-variables may send to wrong directory

Ni!

While debugging a package definition I met the following odd behavior:

On subsequent failed builds, if I go to build dir and source

'environment-variables', this is what happens:

/tmp/guix-build-[package].drv-1$ source environment-variables

/tmp/guix-build-[package].drv-0/[package]$

See how I source it in failed build '-1', but my cwd gets changed to

failed build '-0'!

Cheers,

ale

Alexandre,

If Guix used a different build directory depending on how many

previous builds were kept, many builds would become

irreproducible.

Instead, Guix always uses .drv-0 inside the build container. When

you pass --keep and the build fails and .drv-0 already exists on

the host, it's renamed.

If you want ‘environment-variables’ to match the environment

outside of the container, rename /tmp/guix-build-[package].drv-1

to /tmp/guix-build-[package].drv-0.

Kind regards,

Ni! I see. Thanks for the explanation. .~´
