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'!
