bug#47919: Sourcing environment-variables may send to wrong directory

[Alexandre Hannud Abdo]

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
