Hello,

thank you very much for these snippets. I'm a lazy guy :-) so I wrapped
this into a script, which starts a new bash with this environment (see
attachment). Maybe this could be enhanced using guix mechanisms?
Suggestions are welcome.

Usage:

./pkg-env  # go into latest failed build - very convenient :-)
./pkg-env  some-package # go into latest failed build of this package
./pkg-env /tmp/guix-build-some-package-1.4.01.drv-1 # go into this directory

> That would probably make a good “Debugging Build Failures” section.

Absolutely!
