Looking at that list I feel like I'm missing bits. If we go down the
rabiit hole of figuring out all the different files which could possibly
be included in the list I feel like we should keep it as a fancy macro
somewhere. It'd almost be easier to copy the entire directory somewhere,
run 'git clean -dfx' and then use that. Or to parse .gitignore or make
clean.

Returning a list also seems to work
(ins)efraim <at> 3900XT ~/workspace/shepherd$ guix build -f build-aux/guix.scm -n
substitute: updating substitutes from 'https://ci.guix.gnu.org'... 100.0%
substitute: updating substitutes from 'https://bayfront.guix.gnu.org'... 100.0%
The following derivations would be built:
/gnu/store/g2ql360i3s02mg42l4ys27lsghpx5xqq-shepherd-0.8.1-HEAD.b482009.drv
/gnu/store/ajlqc21qqmi3fp5j30jq7vc0i1qn701y-guile2.2-shepherd-0.8.1-HEAD.b482009.drv

Technically it works, but it's not as useful as just getting the inputs
you actually want.
(ins)efraim <at> 3900XT ~/workspace/shepherd$ guix environment -l build-aux/guix.scm
