This works, thanks! Should we document it in `guix size -h`? I think the result is interesting with respect to the discussion we had about shrinking the closure sizes in Guix: --8<---------------cut here---------------start------------->8--- > guix size /gnu/store/alydrspjw3sfc6b01kyz30vjhjrny86c-system store item total self /gnu/store/w8gjhcw6a16rk1dvxa97bz2znal5fihm-go-1.13.9 639.1 350.7 6.8% /gnu/store/9qs1v87rv4ch7x07adbx8pfnkjxm39d1-guix-1.1.0-4.bdc801e 467.8 268.9 5.2% /gnu/store/cpx45dbix533r2yx73jbv8fd0h8c3vyn-linux-5.4.41 244.0 244.0 4.7% /gnu/store/6hnk449wv8vhbrm0in0ychqiwipsqyza-docker-19.03.7 1245.3 195.7 3.8% /gnu/store/n08as2lvmcc14q57bq1z8p7r1kaa1vv2-gnome-getting-started-docs-3.32.2 164.0 164.0 3.2% /gnu/store/skxkrhgn9z0fg9hmnbcyfdgzs5w4ryrr-llvm-9.0.1 199.9 128.5 2.5% /gnu/store/da1lys4i2yxl549iwkbdg1fb7azphniw-emacs-26.3 1181.3 128.1 2.5% /gnu/store/8jn365r0kk69j1f4b1q2b7aa2qm1xvg1-mesa-19.3.4 341.6 114.6 2.2% /gnu/store/rn75fm7adgx3pw5j8pg3bczfqq1y17lk-gcc-7.5.0 178.5 107.3 2.1% /gnu/store/rsjdq6b0csxc16mbapx5yvrc2zrk20za-containerd-1.2.5 755.7 105.9 2.0% /gnu/store/vnivzyfy0bcxz8rn9gasav5k7skax57y-samba-4.12.2 594.1 98.8 1.9% /gnu/store/1hrwdsd5fwn3xmdgnpyg2h1j5jr6q8ws-webkitgtk-2.28.2 930.4 98.2 1.9% /gnu/store/znly83q0jmcqg6ppwbz5marj5ix9vkk2-locale-2.31 91.9 91.9 1.8% /gnu/store/ikcjpg1y0mb5qinpdc0q85xvm53cz80q-locale-2.28 91.8 91.8 1.8% /gnu/store/09a5iq080g9b641jyl363dr5jkkvnhcn-python-3.8.2 171.4 79.8 1.5% /gnu/store/fj33c1nw4v81qcd33wp53f3aa01g3m9d-ibus-1.5.22 946.2 66.3 1.3% /gnu/store/sd278fsdfx5hjrcgncflnp9qq4l42p1c-python2-2.7.17 151.7 61.1 1.2% /gnu/store/8zvc5mvk0xm3ygrxsgpyy5ilxb5rzjry-perl-5.30.2 146.2 57.1 1.1% /gnu/store/lvnv80g5iqf7fqlckadjfrad9999d4f7-mozjs-60.2.3-2 248.3 54.7 1.1% /gnu/store/ljcrz0d86r20phszvj6s1mdyjchz79ja-guile-static-stripped-3.0.2 54.7 54.7 1.1% /gnu/store/m1z7cdbqsqyp9xnjw5cvlb4a7gkcg3m4-binutils-2.34 93.0 54.6 1.1% /gnu/store/18hp7flyb3yid3yp49i6qcdq0sbi5l1n-guile-3.0.2 132.8 53.2 1.0% /gnu/store/0m0vd873jp61lcm4xa3ljdgx381qa782-guile-3.0.2 132.8 53.2 1.0% /gnu/store/fii66zlqdzv3kbfdbzmj33vvxfwvj33h-gnome-user-docs-3.32.3 49.9 49.9 1.0% [...] --8<---------------cut here---------------end--------------->8--- - go: I think I've got go because of docker, but go should be a build-time dependency, I don't think it belong here. - llvm: I think it's mostly dragged by Mesa. Mesa depends on some LLVM libs, but not all of llvm: https://www.archlinux.org/packages/extra/x86_64/mesa/ Moving the llvm libs to a "lib" output could reduce the closure size of many packages I believe.
