Emacs closure at ~900MB?

[zimoun <zimon.toutoune@gmail.com>]

Dear,

I am building Docker images containing only Emacs and I find them really
big –– and I have a low upload bandwidth.

Well, using Guix 9e7b265, “guix size emacs” says:

--8<---------------cut here---------------start------------->8---

total: 859.7 MiB

And I am surprised to see the package ’llvm’.  Is it expected?  This
package is dragged by mesa, dragged by gtk+.

--8<---------------cut here---------------start------------->8---
$ guix graph --path emacs llvm
emacs@27.1
gtk+@3.24.20
mesa@20.0.7
llvm@10.0.0
--8<---------------cut here---------------end--------------->8---

Is it possible to reduce the closure size of Emacs?


All the best,
simon
